Default PT Cruiser new owner needs help!

Hi, am the proud owner of a 2002 PT cruiser kept in immaculate condition by the previous owner. Sadly, things need replacing and repairing and we are struggling with a fan problem.
The fan isn't kicking in when the car overheats; changed a temperature sensor, my mechanic has had his electronics on it and can get the fan working via his gadget. We have tested the low speed relay and that's working, doesn't seem to be a way of testing the high speed one so have ordered a new one.
Not convinced that's the problem as when it's plugged into the gadget it is clicking so trying to start the fan.
My mechanic has never worked on one of these cars before but seems to think that there is another temperature sensor between the engine body and the fan - he can't quite reach it.
Any ideas out there?
My local Chrysler dealer is useless and the next one is quite some distance away; with a faulty fan I don't want to risk driving it that far.

Welcome to the forum.

Hi speed fan comes on with the AC on and is also controlled by pressure switch on the accumulator.
These fan seem to last about 100,000 miles and need replaced because the brushes wear out.
The harness connector sometimes get hot , probably from a combination of loose
connection and brushes wearing out causing heat and melting the inside of the harness connector causing intermittent operation.

Please don't over heat the engine.

Good info above. Try hot wiring the fan at the plug from the battery. This way you can test high and low on the fan. Has a set of brushes for both speeds. Fan is the most likely culprit.

With the engine cold, start the engine, turn on the A/C. Does the radiator fan come on almost immediately as JoeX posted ? If not manually check the radiator fan by applying 12 volts to the low speed and high speed as Busted_PT has posted and post back what you find.

You should be able to test the high speed on the radiator fan by pulling the low speed relay, start the engine and the high speed should almost immediately start running. You will trigger the code for the low speed not working so just reset it with the OBDII Scan Tool.

PT's came with a mixed bag of electrical gremlins from the factory. In their latter years, after they've stopped being properly maintained, the gremlins show up randomly.
Because of the lack of knowledge among DIY-ers (and garages) what you can find - as I did with my 2001 petrol - is that all sorts of bodgery and silly buggers has taken place, usually done people who nobody sane would allow near their car with a toolbox.
Trying to work out why my low speed wouldn't come on, I discovered all sorts of places where some muppet or other had "spliced" into the electrical wiring in an effort to by-pass everything and get the fan to run.
By "splice", I mean he had bared half inch sections of the insulation and twirled new bits of wire onto them to try and get it to run via add-on relays - and then left the "splices" bare......
In a nutshell, the fans go bad. They're a fan. Fans go bad.
Take the airbox out.
Find the connector plug between the loom and the fan assembly, pull it apart from itself. This is a cow, because it's down low, but it's doable.
In the plugs, you'll see 3 connectors.
One is low speed.
One is high speed.
The middle is earth.
Run a (fused!) wire from the battery positive.
Touch each of the *outer* pins in the plug.
If both pins make the fan work, your fan is OK. If not, you probably have the answer: new fan assembly.
There ARE bodges you can do that don't involve hacking around the wiring.

1) run a (fused!) relay from the low wire, so that when the engine says I want low fan, takes a signal from the low fan wire and sends voltage to the high wire and you get high speed fan instead.

2) Hotwire the high speed fan to a switch in the car via a relay.

3) Swap the wires over near the plug, so when the car asks for low speed it gets high speed.

BUT - by the time you've done any of those - you might as well have done the job properly and bought a new fan assembly of eBay and whacked it in - because - for example - the air con relies on the high speed fan running, and if you start messing around with the wiring you *could* wake up another load of gremlins that will cost you even more.

It's an easy job a monkey could do in an hour, and the cars electrics remain standard. Yes, it might cost you a one-er - but that will be cheap compared to trying to work out why something else (eg, your air con) has stopped working.

My 2001 PT overheated for two reasons. Firstly, my thermostat was shot, did not open when boiled in a pot for 30 minutes. The other cause was the radiator fan motor. Brushes and commutator were completely busted. My PT has over 150k miles, so it was overdue. Replaced just the motor, $70.00 at O'R.

Anytime an engine is overheated the thermostat will most likely be damaged. Its very common for the radiator fan to fail first and then cause the thermostat to go bad.
