What Umberbr was referring to was a serpentine belt which drives the accessories, not a timing belt… If this is a 2001 Toyota Celica GT I am going to assume it has a 1.8L engine…
On the 1.8 the belt tensioner is known to go bad… Not saying that is your issue just yet.. You are correct, it has a timing chain driving the camshafts…
The A/C light on a Toyota will blink when it is low on refrigerant/rapid cycling of the A/C Compressor… It may work in the cool mornings with a cool engine, but not later in the trip when the engine heats up or the day heats up…
The U.S. is now going through a “Polar Vortex” with cooler than average temperatures… that is why it could be working now (if you are in the U.S.)… A/C works at certain temperatures and humidity…
Since the A/C compressor on this is a NipponDenso unit here is what I advise, and I don’t say this lightly… Get one of those A/C freon bottles they sell at the auto parts store and set the temperature on the pressure dial to the ambient air temperature… Hook it up to your low pressure port and check the pressure… I would bet it is low… The reasons are too numerous to explain, but if you want A/C the rest of the summer try it… Add refrigerant until it meets the ambient air temperature you set (it is a rotating wheel over low pressure) which should be between 20 and 45 psi. Also, do not overfill… Refrigerant is not like sex and beer (more is better)…
Toyota A/C systems leak in different locations… But very slowly… This is the only reason I advise A/C fix in a bottle and it should be the only time it is used….
Let us know how it works…

is it easy to use those freon bottle thing? I think I saw a video of it as just plug n go. Is it as easy as changing air/cabin filter? I’d have to learn this myself. It’s my first time doing so and first time doing something for the AC, as I never had to.
In the future if you have other issues outside of the listed topic please post them to a new thread.
I will once again urge you to take this problem to a professional. AC work is not for the inexperienced. Based on your responses, I think you may fall into that category. I’m not trying to be insulting, just realistic. If nothing else please read through this article.

Good luck and keep us posted.
OK the blinking AC light came back on, I would turn it off and on again to see if it would stop blinking. It didn’t for a day or two but so far it has disappeared again. I haven’t check the AC refrigerant yet.
A buddy of mine said it could be electrical. Is it a fuse problem? The AC stopped blinking and everything seem fine other than the windshield gets all foggy even when I had my defogger/defroster turned on. It’s cold out. Everything seem to work fine. The fogginess disappears somehow when driving.
[quote=”ToyotaKarl” post=104791][quote=”bananaspree” post=104752]Ok the issue seems to have been resolved without me do:ing anything. Not sure if that was just a glitch or an indication of future problem.[/quote]
Not trying to sound negative, but honestly have to say this…. Car problems don’t fix themselves… If it happened once, it can and more than likely will happen again…
