Default Re: Code Trouble
The A/C head pressure switch closes to ground at apprximately 210 psi. When the head pressure switch completes circuit 603 to ground, the fans should run at high speeds. If a code 69 is set, the engine cooling fans will run on high speed anytime A/C is reguested.

Good luck,
Sellncars
