Help me please my a.c does not work
Please help me. I bought a 89 c4 last year (car is converted to accept normal/new a.c fluid) and the ac at the time worked but stayed on even when you turn the car off so basically if you wanted it off you would have to unplug the cables from the "Blower control module". I looked it up and some guy on YouTube (I'll link the video at the end) said I need a new blower control module so I bought one, installed it and now I get NO AIR AT ALL. Please help me it's so hot outside

Make sure you have the correct module. The 86-89 module is internally different than the 90-92 module. They look the same and will plug in but the compressor will not run if you install a later module in an early car. The compressor relay is not installed in the later modules. I spent many hours troubleshooting my compressor problem before I discoverd this. Some sellers incorrectly list them as the same.
