Air Conditioning Not Working
 

Hello All. Air conditioning not working in my 1987 Camry with 2.0 L engine. Here's what I know:

1) Have had car since 1992. Mother-in-law bought it new. A/C worked fabulous for the 30 years.
2) About 2 or so years ago, it would not cool when at idle. I don't recall or didn't check if the compressor was on at that time. Above idle, arctic cold.
3) At the beginning of this year, started just blowing hot air. Compressor turns on when AC button is pushed (and lights), but only hot air. Fan works fine.
4) I believe it has never been retrofitted to R34a as I never recall doing that and the fittings look like tire valves.

Help needed. Much appreciated.

Check for:
Low Freon.
Debris in condensor and evaporator coils.
Air mix door issues. Door blends hot and cold air to get desired temp.

Thanks Joey P.

Hey all. Does anyone have the the P/N and/or a source for the "AC MG RELAY" located in the fuse/relay box on the drivers side of the engine bay? My AC indicator lamp is blinking and the compressor is not engaging. Was working fine until I started fooling with things to see why my left side fan was not turning on (I assume the AC fan is on the driver's side). The fan works when I hot wire it and I got the compressor to kick on when I jump the connectors in the noted relay. Also noted that the left side fan started when I jump the terminals, but would quickly stop. I added RF134A replacement to the proper level and when it works it is blowing cold air. Anyway, help appreciated.

Is this it?

Thanks Joey P but none of those pin configurations match my relay.

Does the current A/C relay have a part number on it? If so do an internet search on the part number.

The relay that is currently in there is a "dimmer relay". I may have replaced this years ago and was unable to find the right part back then as well. I'm going to try another dimmer relay and then call Toyota parts to try and get some "free" guidance.

It is possible the A/C relay is also used someplace else. So try another dimmer relay.

Still having issue with my 1987's AC. Does anyone have the the P/N and/or a source for the "AC MG RELAY" located in the fuse/relay box on the drivers side of the engine bay? It is the rectangular one closest to the front of the car. Thank you.
