Tom Greenleaf Ultimate Carjunky / Moderator Aug 17, 2008, 7:19 PM Post #2 of 5 (1655 views) Re: ford F150 1997 air gets hot ??? Sign In Hmmm?? That's a new one! Not real sure just how to check that out. There is a blend door for temp adjustment. For the moment I'm thinking the control knob (hope separate from control head) is somehow sending the wrong request?? Is this actual "warm" air or just not cooled air if you can tell? Does it reset if you restart the truck? T Jeff Norfolk Enthusiast Aug 17, 2008, 7:44 PM Post #3 of 5 (1651 views) Re: ford F150 1997 air gets hot ??? Sign In This may be blend door actuator failure. Typically when the actuator fails it will fail to heat rather than A/C. The actuator will have 5 wires running to it. One black for ground, one lt blue/pink for power(hot in run), And three control wires. These control wires will have a variable voltage signal coming from the selector switch. The red/lt green will be high voltage when selector is all the way on cold. `The red/white will be high voltage when the selector is on heat. Check for power and ground at actuator. Then put selector on cold and back probe wires on actuator at the red/lt green wire. Should be high voltage at start up. If voltage dose not change but the temp dose then the actuator is probably bad. If the voltage changes then check voltage at red/white wire. If high voltage is present then selector is probably bad and sending the wrong signal. Good Luck.

Sign In most likely a vacum leak either on a canister,line or switch itself Jeff Norfolk Enthusiast Aug 20, 2008, 3:59 PM Post #5 of 5 (1631 views) Re: ford F150 1997 air gets hot ??? Sign In I don't think the blend door is controlled by vaccum.
