Re: How to properly drain a compressor?

Invert it to drain and also rotate the clutch hub. Pour new oil into the suction port and rotates it.

Re: 02 Passat slow leak through evaporator. Dye question

not all UV lights are the same. Try looking at the condensate drain tube at night. Also, the dye and light you're using may require yellow glasses.

Re: 1978 corvette r134 conversion

Corvettes are a poor choice for conversions. Four seasons are a poor choice for parts. You're dead in the water before you begin. You will need to upgrade the condenser also. Better do your due diligence before a decision is made.

Re: Chrysler minivan a/c mechanically good, but no cold air

Take a relay apart and use it as a test. Make sure the connecting pins are making contact. You can use a clip lead to make and unmake the relay connections. make SURE you are on the correct terminals.

Re: A/C Pressures - Opinion

Pull the charge and re charge by weight. That will eliminate charge as a source. It might even fix it.
