Gen1 A/C help please

Hello All,
I have a 95 Avy that was rarely used but now is my daily driver. The problem is the AC only blows cold at night or morning i guess when it isnt burning up outside. If it helps at one point the AC button light was blinking and ac would not blow cold to fix this i would turn off ac for a while then turn it back on and it would work again. Also the button will not lock in the ac position so i just wedge a small piece of paper to make it stick. I never had the ac recharged and as far as i know the previous owner didnt either. Can this be culprit ? (hope so this is the cheapest solution) Also can i use one of those DIY kits from the auto parts place ?
Youre help is greatly appreciated.

Does your 95 have a sight glass where you can watch the refrigerant when the A/C is running?

Follow the small diameter line from the compressor to the condenser. Then follow the small diameter line from the condenser to the drier. If you have a sight glass, it will most likely be in the line between the condenser and drier or mounted as an integral part of the drier. If you have a bad on/off switch, you may have damaged the compressor by repeatedly turning it on and off.

It is a common thing on Toyota's for the air conditioning to go after more than 6-7 years. It's usually the compressor/drier/condenser that has to be replaced. It went out on mine. You could try topping off the refrigerant, but it will only last you about a month or so before it goes back to the same thing.

It's kind of expensive to have that all replaced. About $350 in parts plus the labor. Then again, yours might just be low on refrigerant, but that would mean you also have a leak in the system.

I assume you mean the condenser OR the compressor. The drier doesn't go bad unless the system has been open and exposed to moist air for an extended period. I have driven nothing but Toyota/Lexus cars for over 35 years (7 different cars) and I drive them for at least 13 yrs/150k miles. I have never had a compressor go bad. Also, I read several different Toyota/Lexus car forums and do not recall anyone having a compressor failure. I believe an A/C compressor failure on a 6-7 year old Toyota would be a very rare event. I have had two condenser failures, both times from road debris.

Yes, I do mean the condenser or compressor. A lot of places will give you a good price on the combo of the compressor, drier, and expansion valve, so it's not a bad idea to just replace them while you are at it.

Where I used to work, we saw at least a couple Toyota's come in a year for AC service that needed a new compressor/condenser. Not that it happens to every car, but it isn't uncommon.

I just re-read your post and you said that you had to wedge something in to keep the button in place...it might be just that the button isn't quite working and isn't really activating the AC; you should look into seeing if that button is the culprit.
