1986 Jeep Greand Wagoneer
I am having a problem with my heater. The unit does not open the
vents. The motor works as does the temperature slide. The problem is the top slide does not redirect the air for defrost heat etc. It will switch to air conditioning though. It appears to be vacuum activated and all hoses and port appear fine. Where is the vacuum source for this and how do I reconect it? Thanks in advance. |

Going to be a tedious job, probably most of the vacuum hoses will be
cracked as they leave the intake manifold ports on a twenty year old car.

Re: 1986 Jeep Greand Wagoneer
I'm betting on the servo for the defrost being defunct. You can test
these with a cheap vacuum pump and a piece of hose. Gaining access will be the difficult part. Cheers, Earle "L.W.
