Guys,
With all of the vast experience and knowledge out there I was hoping you could help me (grin). Above my plentum, mouted on the firewall, is a plastic u shaped valve. It seems to regulate the flow of hot water from the engine to the heater core. It has a cable that goes right into the firewall, but I cant seem to find where it ends up. The reason I say is because the cable is in the position where it is in all of the way to the firewall, but I cant figure out what controls it. Common sense tells me that it goes to the heater control, (hot cold), but when I move it back and forth it does not move the valve position. I had to replace my 4x4 dash light, so i have half the dash apart, and want to fix this if it needs fixin! The heater control on the dash does move vents, and I can see the cable does down to the passenger side, and controls linkage, but it does not move this valve. Anyone have experience with this?

 

the warm to cold heater control should move your valve on the firewall.. something must be broke somewhere..

 

Yeah,
I figured it out, the little nub on the cable to the valve broke and it came loose. How hard is it to replace that cable?

 

umm.. that i couldnt say.. never had too.. if you could somehow make it work id go with that first.. maybe someone who has changed one will chime in...

good luck..

Ive replaced a couple of those cables, if you have a pic n pull near you, you should be able to find one there.

 

Thanks
