Asked by Jun 25, 2014 at 07:19 PM about the 1994 GMC Sierra 1500

Question type: Maintenance & Repair

well the A/C does not work for one. It leaks freon... but the heater core leaks inside the
cab. so i just want to bypass it altogether?

If you want to bypass the heater core, just add a new some hose to bypass the core. You probably can't bypass the AC compressor without a aftermarket bracket to get the belt to ride over all the accessories. Having the belt ride on the Compressor and not using the AC won't hurt anything unless the pulley is frozen.
