A/C logicon
I have a 90 vert had it in the shop for about 2 months doing a full t2 swap this tuesday we finaly started the car and the a/c logicon worked fine but no cold air because i changed the stock ecu for a haltech and from what i've heard the stock ecu controls the a/c compresor. wednesday went to the shop started the car and nothing in the a/c logicon worked is there anything that controls the logicon

The stock ECU won't let the air conditioning compressor to turn on, if there is insufficient freon pressure.
However the logicon is not controlled or effected by the stock ECU other than switching the A/C compressor on or off based on freon and switch position.
So if the haltech was put in, you will need to bypass the ECU control on the air conditioning compressor, but other than that the logicon should control everything else just fine.

Okay, there are two wires that power the Logicon, the White/Green (12 volts + constant) and Blue/Black (12 volts switched ignition.
Both need to have power on them when the key is on, for the Logicon to work.
