Default No A/C on non-turbo '01

We've had our first few hot days and guess what? No A/C! At the end of last summer I had a/c issues that were caused by a bad radiator fan. Replaced the fan and everything was fine. Later in the fall, I replaced the timing belt. I was able to do it without disconnecting the a/c system (just pulled things out of the way). I can't recall if I ever ran the a/c after that.

Anyway, right now when I turn on the a/c there is absolutely no response. There is no sound of the clutch engaging. I haven't noticed the condenser fan turning on either. I thought that the coolant might be low, so I put on my charging kit, turned on the a/c full blast, and...nothing. No coolant went into the system. The gauge is in the red, I'm guessing b/c the compressor isn't running.

I checked the 10A fuse and relay under the hood and they are good.I am wondering if lifting and dropping the motor during the timing belt swap may have done something to the compressor. My next plan is to get under the car to check the wiring. I might even run a jumper to the compressor to check to see if it functions. Any other thoughts would be a help!

Thanks everyone!

try adding refrigerant. the compressor will not engage if there is not adequate pressure.

mine has a slow leak somewhere. the compressor will begin to cycle on and off as it fills.

before adding any refrigerant, push in the valve on the line and see if there's any pressure. if it's completely dead, check the underhood sticker for the correct amount and make sure you buy enough. when it feels cold, stop filling it. too much pressure in the compressor will strain the engine, it will shake noticeably at idle and the AC will not be as cold.

I would check the high pressure switch and make sure it is working. If it has failed or got damaged during the timing belt install it will shut the whole system down.

When you turn A/C on does the cooling fan come on?

I hope you remembered to unplug the switch on the back of the compressor (I believe it is the high pressure safety switch).

It is easily missed, and when you jack up the motor it is going to break..... and whala no AC.

When I repaired the head on mine, the previous "mechanic" did not do so when he did the timing belt for the previous owner, and attempted to glue it.

Needless to say the glue did not hold, and I had to repair it. Now I have AC.

Hi everyone. The first thing I did was try to add freon. The system wouldn't take any from my full can (and yes I remembered to open the valve ). My gauge was in the red. I have read that this is probably due to the system having coolant and the compressor not running.

By cooling fan, do you mean the secondary or condenser fan? If so, no it doesn't activate.

Unfortunately, I didn't disconnect the high pressure switch. Dang! You know, I think I remember hearing a plastic like snap sound when we raised or lowered the engine one of the times. I'll check that out when I get the next chance. Rain has been keeping me from looking into the situation more. Is the switch a coupling type deal that is easily replaced, or am I looking at a total coolant evac. and charge?

Thanks for the feedback and info!

DING DING DING DING....that's your problem.

Gotta have that switch plugged in or nothing will happen. When the motor rises, the plug runs into the radiator, and the radiator is not very forgiving.
Being you don't see it from the top it is very easy to do.

As a matter of fact the service manual mentions that first, to unplug the high pressure switch during the timing belt replacement procedure.

Mine was already broke, and the way it broke, you'd have to replace the compressor, because it broke the switch flush with the plug, and the switch is a part of the compressor. I had to do some creative band aiding to get it to stay attached.

You will have to get underneath your car and look to see the severity of the damage.

When I discovered it, I jumped the plug to see if the AC would fire up, and it did.

Thanks for the help everyone! Motorhead, you get the gold star today! Jacked up the pt and what do I see? I little connector hanging down in front of me. Get this...the switch was fine. The connector just popped out! I plugged it in, it snapped into place, and it stayed put. Talk about relief! A/C works fine now.

Thanks again!

Maybe the Freon has run out.
