timing belt change and ac not working - Toyota Nation Forum : Toyota Car and Truck Forums

A couple of days before we took my wife's 93 camry in for regular timing belt change at the local dealer in Santa Fe, we used AC. After the timing belt change, the AC is just blowing hot air and it doesn't feel like the compressor is engaging. I can usually feel if AC is engaged by a little tug at the engine rpm.

Is there anything in the timing belt change that might mess up A/C? I am a little ticked off right now.

Thanks for help.

it depends.....when they were doing the timing belt, they may have also done hte ac/alternator belt and the power streering belt while they were at it.....

but I'm not sure, but if your alternator is still working, then it might actually be the ac unit cuz they use the same belt...? somebody correct me if I'm wrong

You are right... they changed fan belts while they were changing the timing belt.

have a look at those, you may need to tighten up your belt, check your fuses too, i think a/c has a big honking fuse under the hood

this happend when i had my corolla s timing belt changed..... they forgot to plug the ac compresor back in... there was a plug just hanging by the compresor and ii plluged it in and it worked.

Oldman,

forgot about the fuses. I definitely check them out when I get home. Thank you.

Cbra928,

What your saying intrigues me.... Can you explain more about how to put this plug back in?

Is it reachable from the top or do I have to get under the car to reach the plug?

What does it look like? Is it a black rubber plug or metal cap?

Thanks for the info.

its just like anyother plug, find ur compresor and see if there is some thing that not pluged in then look around for the plug should be close to it, in my corolla the AC was right up front, i havent looked at my camry to see where it is.

good luck

either its the a/c fuse, the plug on the a/c compressor, or the belt is loose, but if the belt is loose then the alternator wouldnt be running either, sooooooo... you would have a low battery and find it hard to start the car in that case... check all 3.

Check all relays : 1 is near the passenger door (right from the handglov) and there are 2 others for the fan under the bonnet

Well....

I checked the compressor plug and the fuses related to A/C. Should I check the fuses for the fans also?

How do I check if relay is functioning?

Thank you all for your help.

your compressor could be failing too

Nico · 03-24-2004, 12:46 PM

In fact there is nothing in the timing belt change that could have dammaged your a/c system. It is probably just a low charge problem. I would check its pressure

Thank you everyone for your help.

I took it to a reliable mechanic and he diagnosed it as no freon in the system for a starter. We will see how big and costly the leak is.
