Heater project(s)
#21
So I finally got the heater cable clamps in my hands and installed on the heat (Cool - - - Warm) control cable. The lever and the inner cable now both move freely and are attached to the heater control assembly – I can see them move. The other levers and cables seem to work and operate correctly – I can hear the doors/diverters move under the dash.
But I have a problem – the heat control valve (under the hood) does not move when the heat (Cool - - - Warm) control lever is moved. It doesn’t even act like a cable is attached.
Keep in mind I’ve rarely used the heat or A/C in this truck. So my question is:
Is the heat (Cool - - - Warm) control lever supposed to operate the heat control valve (under the hood)?
a. If it does, does the cable go directly to the heat control valve (under the hood) or is there something/part in between?

I know that my '87 and '88 4Runners have two cables attached to the temp control lever. When the lever is moved, one cable opens or closes the hot water valve while the other one opens or closes the air blend door at the same time.
Not sure about earlier model trucks.

I looked up the part and it is:"CABLE SUB-ASSY, WATER VALVE CONTROL" Part Number: 55907-89116
It looks like it costs about $12 - not too bad.
I also searched here for a post, possibly by Terry, on how to R & R the cable without a lot of hassle but I couldn't find it.
I think I'm going to use the old cable to pull the new one into place.

When I remove a heater control from the dash, I tie some binder twine, or tough fishing line to the far end of each cable as I disconnect them and use the line to guide the cables back exactly the way they had been run before when it goes back together..

I am going to upgrade to the later plastic water valve while I'm at it.
Thank you
