1986 DeVille / Fleetwood. I just picked up this car so i dont know much of its history other than I found a reciept that a new condensor/accumulator and recharge of 134A was done appx 10k miles ago.

when i turn the on the AC, the air doesnt get cold. Fan works lo/hi and i can bump the temp by hand down to 60*, but the air dont get cold. the fuse for the AC is good.

whats the easiest / cheapest way to diagnose why its not cold.

thanks

Put a set of gauges on the service ports and get the high and low side pressure readings.

I have an 87 DeVille 4 door, and my problem with the AC is lack of real air movement from the vents. Blower motor sounds powerful enough.Does yours have a good air flow out of the vents? Just curious. Sounds like your problem should be an easy fix. I am still searching for vacuum leak or problem with one of the doors that direct the air. Real Bit#ch to move around under dash. LOL.

Check the HVAC housing on the firewall. If it has gotten brittle and cracked, then all the air is being diverted under the hood.
