a/c not working because of tune?
I have a 2002 silverado with a speed density tune. The tuner said he used a "camaro file" to tune it. the a/c no longer works. i have narrowed down the problem to the computer not sending a ground on pin 43 c2 to the relay for the a/c compressor clutch. is this a problem due to the "camaro file"? or should i just bypass the computer and run the high pressure switch to a new relay that controls the compressor?

There are some things that will prevent A/C engagement
(like unstable idle, in stall saver).
Camaros use a pressure sensor value, not a low pressure
switch. There may be something there, compatibility-wise.
