A/C light blinks on and off

Paid a high price just today for the same problem. There is the clutch relay in the Fuse and Relay box under the hood. When it's going bad, it will work and then not work and so on. It's very inexpensive to change, just you must get it at the dealer and it MIGHT be $25. I paid $170 today to get mine fixed @ Toyota and I hope this helps to save someone else some dollars.

Light came on until about a week ago. A/C blows but its warm air. A/C light has only come on twice in last 2 weeks. It used to even come on when I set HEAT to "Auto".

Called dealership and they mentioned it may be the relay. Where is the relay and is it labled?

I already checked and replaced the fuse (it was still a good fuse).

Hello Joe. Thank you for you answer. I should have provided more information in my question. As far as I can tell I have 2 relay blocks under the hood and 1 fuse box in the cabin of the car. None of the relay blocks have anything on them that indicate A/C on the underside of the lid covering box. So when I ask where is the relay, I mean very specifically.

Did I mention when I called the dealership, they also mentioned it possibly being the relay. I would very much like to replace that 1st rather than take it somewhere.

Yes, the A/C was ice cold. Many times I would have to crack a window or sunroof when it ran.

I ran it most recently less than 45 days ago. It worked just fine then.

Hearing the compressor; I hear the same amount of noise now as I did when I ran the A/C previously. So I guess I hear it (shrugs) however, I do not feel the adjustment in how the vehicle runs when I cut it on. I used to feel it as if less power was in the performance of the vehicle.

Thanks. Hope you had a Happy Easter as well. No this did not help me at all. I print it, I cant see it, I blow it up, I cant see it. So am I to understand that I dont have a regular old A/C relay that I can pull out with some vice grips (yoink!) And pop a new one back in?

I did find some additional relays but they were for something else other than the A/C. Also according to a part that I googled which says its my A/C relay (as per a different site) the prongs were different. That site did not give the location where the relay should go either.

I just need to know specifically where the A/C relay goes. Unfortunately I live in the TAlanta are and the pollen count is 1600+ so I will have to take the car in to have someone look at the A/C by Wed of this week becasue I can not continue to have the windows down and ride without sever reprecussions to my respiratory function.

If you can, please advise. If not, I understand.

Thanks.

The fan for the a/c stopped working

I dont think it will help. I dont even see the relays to which you are referring. Per the manual and all other sources I have checked there should be no additional relays. I have been informed that the relay that controls the A/C is the MG/CLT relay.

The vehicle will be taken to an A/C repair place this morning and I have my father's truck. Because of the extremely high pollen count (6000), I was going to soon have a respiratory issue.

Thank you for your replies but they had me no closer to a resolution than I was prior to posting the question.

I have owned my 1997 Toyota Avalon for 10 years and it has 269,433 miles on its V6 engine. It runs great and only uses about a quart of oil every 5,000 miles.

My question or problem lies with the air conditioner. Recently it will only cool for about 3 hours (I make long runs between Houston & Dallas) and then blow hot air. I tried turning the thermostat to 75 deg. And keeping the blower on low and this seems to at least keep the car reansonably cool. If the thermostat is turned down lower and the blower set at mid-range or high then the air conditioner will blow hot air after only an hour. I then tried turning it back to 75 deg. But it still blew hot air. I've had the freon pressure checked and it was OK.

Any ideas?

I have a 98 toyota avalon and the air conditioner has 4 speeds, but only low speed works and it only blows out warm air why? I also read that the high speed bypasses the resistor.
