HVAC (6 OF 6)
Once I had the old blower out, I found the driveshaft was real wobbly so thats what was causing all the racket I heard.
Then I installed a new blower motor and set the hinge back in place. Even with the difficult access, the job only takes a couple of hours or so.
PROBLEM 13: The two barbs on the vacuum reservoir have nothing connected to them.
SOLUTION: I installed a new vacuum supply hose from the reservoir to a spare port on an existing intake manifold tree. I connected a loose hose I found that supplies vacuum to the CU in the cab.
This little schematic in the Service Manual
is quite useful for checking out the vacuum controls.
PROBLEM 14: There are two unconnected vacuum hoses near the heater/AC housing.
SOLUTION: I connected one of them to the vacuum reservoir (Problem 13). I connected the other one to the water valve. I had to lengthen this hose with a new piece of hose and a connector because it wouldnt reach.
PROBLEM 15: The water valve is missing
SOLUTION: I obtained and installed a new water valve
I left a lot of excess vacuum line coiled up for now.
PROBLEM 16: There is no port available on the intake manifold to connect the heater hose.
SOLUTION: I changed the location of the temperature sending unit from the intake manifold to the cylinder head (see TEMPERATURE SENDER REVISITED, below). I then installed a pipe nipple and connected the heater hose where the temperature sender used to be. I had to reroute the fuel line a little.
PROBLEM 17: I cant seem to stop buying parts and fixing stuff on this truck.
SOLUTION: Ill make everything perfect so it will never need another thing.
It took me a while to get there, but once everything was fixed and back in place and I set it to heat
Voila ! I got HEAT ! (I could say this is a very cool thing to have but that would be contradictory).
