Question about 1996 GMC Sierra
I did charge the a/c. I bypass the system by the fuse box, removing the relay and placing a jump wire to run the compressor while recharging. Then when I am done, I replaced the relay and start the engine and turn on the dash board a/c button. THE A/C DID NOT WORK, the blower was turning but no cold air and the compressor clutch don't engage.

Probably the high pressure switch on the accumulator - try disconnecting the connector and jumping the pins to see if the clutch will engage. If that is the problem, DO NOT leave it jumped - replace the switch.
If that is not the problem, you will have to check the clutch wiring, relay and fuse for continuity back to the HVAC controls. If that is OK, the problem will probably be in your HVAC control module.

The A/C pressue switch may be bad as well. Also the mode switch on the control head inside the vehicle. There are many other exsisting problems pertaining to a/c. I suggest a manual from Auto Zone for many faults can be noted especially wiring can be at fault

yes alow presure switch is likely on GM and it could be out of freon ,safe way to tell is to put a set of gauges on it and it will tell by passing the low side switch will just destroy the compressor if it is out of freon

the brake light switch powers the wire which goes to the turn signal switch. So I think if the turn signals works, then the turn signal switch is bad. Check for power at the wire going from the brake switch to the turn signal switch. . Since you didnt tell what year or model the truck is, I cant tell you what the wire color is.
