Re: Go on a diet
I was having trouble getting heat on my 82. Auto Clm H & Ac
Started cheacking per FSM, what a can of worms. sensors to go bad.
Next to impposable to get to water valve.
Didn't want AC [ the P/O had belt off A/C compresor, so figured it didn't work ]
Pulled A/C box betwean fan and heater box, replaced with apiece of inner tube, now I can get to heater.
I wasn't getting vacum through junk at Rt. frount of moter bay, so bypassed it .
Ther are 2 vac. lines from H-AC to moter bay, use the one that makes heater work derectly to int. manafold, and plug the other [ potental vacum leak ]
Good luck
