Porsche 944: My question is in regards XXXXX XXXXX Ac. On my 1986

Resolved Question:

My question is in regards XXXXX XXXXX Ac. On my 1986 Porsche 944 turbo when the ac used to run it used blow cold air then all of a sudden blew hot air instead of cold. Then later it would blow cold again. Any idea what this may be? Do i need to change the compressor?

Welcome! Are you ready to work on your vehicle’s issue now (may need voltmeter and other tools), or just seeking information at this time? Also, is the A/C currently blowing any cold or hot air?

Customer: replied 1 year ago.

Ac was blowing cold air

Expert:  Juan Crespo replied 1 year ago.
I'm sorry for the misunderstanding. If you were to turn the A/C system ON right now, would it blow hot or cold air?
Customer: replied 1 year ago.

that si a good question. because right now I got the starter off because I replaced the master and slaver cylinder. So I do not now till I finish the present job. But maybe you can give me some tips in bleeding the slave an master cylinder. Do I need to buy a pump pressure bleeder canister? to do the job?

Expert:  Juan Crespo replied 1 year ago.

Pressure bleeders work well. However, I've always filled the system from the slave cylinder's bleeder (lowest point) using a long plastic hose and a funnel. Doing it this way requires a lot of patience but it leaves no air trapped in the system.
