Thread: A/C Problem

Tweet

If you move switch on the dash to heat the heat comes on,
but if you move the switch back to A/C it won't work.
So you have to reach under the dash and pull the rod
on the diaphram or accuator on the left then the A/C
will work again. Would this be a bad diapham or would
the contrller or the head be bad.
I am no A/C tec by far so I am guessing here.
This is on a old 83 Dodge pick up.
Thanks for any help.
Kurt

check your vacuum supply to the control head, then pull check with a vacuum gauge to see if vacuum is going to the actuator when it is commanded to

Hey, I'm an "expert" on A/C...when it's hot, roll the windows down when you dirive, when it's really hot, drive faster!!!! When it's Florida hot, stay in the shop and turn the A/C on!!!!! Simple huh? Told ya I was an expert, Kurt!!!!!!!!

Thanks moter I've got to check it out.
