Thanks Strife and CTaylor. I have the setting on Defrost but still no luck (the fan does blow in the cabin though).
When I jump the High Low presssure switch, the aux cooling fan for the engine runs, but the compressor still does not start....
I dont know if the right amount of freon gas is in the system....is it freon (r12) that I would need to charge a stock '87 roadster with do you know ?
Any further advice would be appreciated.
