OK.... refridgerant is OK, switch is OK, and the A/C relay is OK but the compressor is not kicking in.

What else should I check before I come to any conclusions? (I hope its not the damn compressor!)
Any fuses, relays or breakers that I should check?

Im melting here!

TIA
Frank

On the 85 model thier is a relay in the passengers side kick panel. I've had to reset mine on several ocassions. You might want to check this. To reset it, insert a paper clip or tooth pick in the hole, then turn on the a/c.
Good luck

There is probably a fuse associated with it.

Also there is a black wire with a white connector down around the bottom of the battery. This may have come undone.
Alright....checked that connector, its good.
But....Where would fuses for the A/C be?

I dont see anything there that I can stick a toothpick into.

OK...I own an 84, and all I see in the passenger side kick panel is a lil blue fusebox with "A.C" and "HTD Seats" written on it. And that fuse is fine.

And above that, A little black box...not labeled so I dunno what that is.

Am I overlooking something here? Or is that a difference between 84 and 85's

Frank, I believe its a round can type. You are in the right area and it is a relay.
Hope you find it

Does the light in the A/C switch come on when you push the switch to turn on the A/C compressor? If so, then the 30 amp CB in the kick panel and the 10 amp A/C fuse is okay. Is your A/C system fully charged with refrigerant? If the system is low on charge the low pressure switch will open and prevent the compressor from operating. The winding on the A/C clutch may be open as well, or one end of the winding may not be properly grounded.

Thanks Dave....I didnt know that aobut the compressor.

This ended up being the problem. I went through all the steps recomended above, but nothing worked. I took the car to a mechanic friend of mine and had him leak test the system for me, and sure enough it wasnt holding any refridgerant whatsoever. Which wasnt allowing the compressor to work.

The leak is being fixed as I type.
Thanks for the help and suggestions everyone.

I be chillin now! :p

I am selling all the AC parts out of my 82, they work as far as I know but I believe I am just out of coolant so the AC istelf doesnt work. Parts are cheap so if you need anything, let me know.

Update.....The culprit was the expansion valve, So that was replaced. And while I was at it I had the my buddy replace all the o-rings in the system, and of course the filter dryer. System was totally cleaned out and everything lubed up and recharged.

Result.....55 degrees AC temp at Idle, and As low as 38F at highway cruising speeds.

Ahhhh....I love it. 8)



Now unfortunately the car began overheating today :roll: , so I couldnt use the A/C. The damn thermostat is sticking at times. And Its about damn time it craps out too, since it was last replaced in 94. Got a low temp thermostat, and Ill be replacing it in a few hours. Gonna flush coolant system while im at it.

I'm looking for a reputable shop to do a complete AC fix on the Blupra (complete going-over and re-charge) and (hopefully) just a re-charge on the Redpra (with one of the new HC coolants, rather than R134). Anyone know someone local to me (Ventura County or West San Fernando Valley) who does good AC work for a reasonable price? I had one quote recently that was so outrageous that I broke out laughing. I'd do it myself if I had the time and the equipment, but I have neither at the moment.

TIA -- Bob

Total for me, parts and labor was $275

Ive heard through friends of others being charged $400+ for the same type of repairs, at other shops.
