Hi Luisen,
I had copper plate in my work shop, but you could try aluminum from eavestrough or metal from a coke can. The point is create a more durable contact point for the plastic rod to press against. I suggest you rough up the metal on one side to let the epoxy bond well. What we are trying to replicate is the ORIGINAL slope angle so as to be able to disengage the electrical contact (BRIDGE).
The plastic slope angle on the white activating arm of my switch was so badly worn from usage that it could barely break the contact. Therefore the previous owner had to remove the fuse. Just to let you know, I have had my fog lights working trouble free now sine November when I first experimented with this mod. Finally, make sure you grease the plate, as you want to reduce friction.

Daughter borrow my 03 PT Limited and she said the fog lights wouldn't go off. I thought she didn't know how to work the switch, so I tried and it would not go off. She had to turn the left turn signal on to get it to go off.
One night she forgot and it drained the battery. Called AAA and they came and jump started the car. I drove it around and it worked good (fog lights still where on). So my son-in-law took the fuse out of there. Then she noticed that after it was jump started, none of the gauges work, speedometer etc. She drove it again last night and it ran fine. This morning, it won't start again. Going to have it towed to the dealership to have them check it out. Why would the gauges stop working after have it jump started? HELP!

Very possible you blew a fuse. Did you check the interior fuse box for a burnt out fuse for the cluster?

I had that problem with the fog lamps not going off. If I pressed hard on the MF switch they'd turn off. I ended up just pulling Fuse 8.

Question though. Fuese 8 has two functions. FOG LMP & NON BUX. What is NON BUX?

I tried a search and all I could find is other owners asking the same question. I can tell you that of all the people that I've told to pull fuse No#8 because the fog lights wouldn't shut off, no body has ever come back and said something else wasn't working because that fuse was pulled. New owners of used PT's have also said they found the No#8 fuse pulled when they bought the car and the only problem they were having is the fog lights weren't working. So, I wouldn't worry about anything else being affected when pulling the fuse.

Your cruisers are wired up differently because of your laws. I had to add lights and re-wire others to pass your M.O.T. on both my Corvette and Chevy Monza when I had them over there in Harrogate.

Check out the UK forum for PT's. They should have an answer.

This was really helpful, my 2005 ragtop had jsut started loosing its battery cahrge, and I FINALLY figured out my fog lights were turning themselves on. Being able to detach the fuse saved me 400.00!! Thanks! I love my car again!

Old Part# - 04671870AD (2005 PT Convertible, Touring Edition, 2.4L Turbo, With Fog Lights)
New Part# - 05073049AB (dated 12/29/2009, same as back in 6/2007)
Cost to purchase at dealer - $142 including PA tax
Install time – around 30 minutes if you don’t stop to take notes and look things over.

Tools: Phillips screwdriver, small flat screwdriver, T10 & T20 Torx bits/screwdriver

• Put door windows down a couple of inches before disconnecting battery cable so you can open/close the doors without them catching on the rag top. Otherwise the top window edge catches in the recessed groove.
• Remove negative battery cable.
• Move steering column to lowest tilt setting.
• Remove (2) Phillips screws from underside of steering column plastic covering.
• Remove top and bottom covering and set aside. The top part comes off first, while the column is down. There are inside clips on the back end of the top/bottom covering that hold them together. If you push in at the back end (close to dash) on the bottom section you should be able to spring it free while lifting up on the top half. If not, carefully use a flat blade screwdriver from front to back to pop the clip. To get the bottom cover off, raise the steering column and it comes out much easier.
• The order of the next three steps can be *reversed* if there is not a lot of flexability to move the wiring harness around while the multi-function switch (MFS) mechanism is bolted in place.
• To disconnect the wiring harness, take a small flat screwdriver and push the red locking tab toward the engine, straight back. Do not lift on tab. It slides in and out.
• Disconnect wiring harness. Slowly. It should come out relatively easy. If problems, make sure red tab is pulled out as far as it easily slides.
• Remove (2) T20 Torx screws on top, close to steering wheel. Wiggle entire MFS off the posts holding the MFS so it can be moved around some.
• Remove (2) T10 Torx screws on right side by putting screwdriver through steering wheel spokes so the wiper switch can be disconnected.
• Pull wiper switch section out of your way to the right.
• Pull out old MFS.
• There was no dust cover on the 2005 model around the switch stalk.
• Transfer flasher module (not included with new part), on the side where the wiper switch was connected, by pulling it straight out/away from MFS. There are metal tabs on the back that can only be oriented one way to correctly insert it in the new MFS.
• Examine the two wires that come out the back of the MFS, snake around the edge (under hold-downs) and then up the middle of the switch stalk. Rearrange the wires to make it easier for them to move a little bit back and forth for when you move the switch stalk forward to engage high beams. I was concerned that having the wires tight would wear down the insulation and/or weaken the conductor. Don’t know what these two wires do but they do *not* control the fog lights.
• Place MFS back onto column, but not into proper position as you will need to install the wiper control.
• Install wiper switch with the (2) T10 Torx screws that were removed by once again reaching through the steering wheel spokes.
• Place MFS in the proper position on mounting posts.
• Install (2) T20 Torx screws into top mounting holes.
• Reconnect wiring harness. Carefully. Once the connector is fully pushed in, slide the red tab towards the steering wheel to lock the connection.
• Connect the negative battery terminal and test all functions of the switch stalk, 4 way flashers and wiper for proper operation. If any problems, *disconnect* the negative battery terminal and then check the wiring harness for being fully in place. Reconnect battery and try again.
• Install upper and lower plastic covers by moving the column down to put the top half in place and up to put the bottom half in place. Align and push the back ends (both sides) together to re-engage the locking tabs.
• Install (2) lower Phillips screws after aligning the front edge of the halves.
• Check that the column can still move up and down and that all switch functions on the MFS and wipers still work.
• Your done with only cleanup left.

Several other things to note.

• This part also goes under the number of “CBS-1210”. This number will fit a 2005 Cruiser.
• I suggest you pull the 15 AMP fuse for the fog lights from the inside fuse panel if you have any fog light problems in order to insure the lights don’t stay on and drain the battery. It is fuse #8 in a 2005 model. Check the back side of the fuse panel cover to ensure you remove the correct fuse.
• When the problem occurred and I had the fuse still in, headlights on and fog lights on (at least according to the switch position) the fog lights were not on.
• I also noticed that during this time, when I used the turn signals the display on the radio would blink in time with the turn signals.
• After I removed the fog light fuse, the radio display would very seldom blink when I used the turn signals. It always blinked when the fog light fuse was in place after the switch stalk problem started.
• I took apart the original factory installed MFS looking for anything glaring as to why the fog lights did not work. I found no broken parts inside the MFS. There is a plastic dowel down the middle of the stalk that works a leaver that pushes a metal contact up and down. The springs were good, the leaver worked, the stalk was not worn down or broken. There was oxide around one of the two contacts involved with the fog lights but I can’t tell if it was enough to stop electric from flowing. There was a lot of grease type lubricant on a lot of sliding parts inside the switch. Have to wonder about the electrical properties of the grease lubricant and if it was shorting things out or insulating contacts. Maybe it changes properties over time. Pure speculation on my part.

Anyway, my thanks to KG for posting his instructions and showing the way!

There is a fuse box under the bonnet - do not remember which fuse for fog lights but it is labelled.

Thanks for providing this. This is on my list of things to replace on my car. Hopefully I can make this a weekend project and get it done without taking it to repair shop.
