Re: Air, hot and cold
George if you could be a little more specific, where is the control valve and what does it look like. I went out and looked but I didn't see anything that might be it.
I had the problem of the fan speed control being flaky. I saw where someone had a fix for that so I did it thinking it might fix the air problem too. It fixed the fan speed problem but the air problem is still there.
This was not a problem until last Friday, and since.

It is circled in yellow : ( one hose going to it, two hoses coming from it to the two heater cores.
They work kinda bass-akwards, 12v is supplied to the solenoids, ground on other side means STOP flow, no ground = ALLOW flow.
The control module sends appropriate ground pulses to match the position you have the dial wheels in.

Re: Air, hot and cold
After getting sidetracked several times,I got back to the problem. The one on the right (looking back as in the picture) is hot the one on the left is not.
From my understanding of the schematic they are both sides powered by the same fuse. I had the controls out yesterday and looked it over good. So. if the solenoid is not working, it looks like a replacement is in order. Is the unit I was feeling of the part that needs replacing?

Re: Air, hot and cold
Yea, I try to save my smart-*** answers for smart-*** people, you didn't qualify there so I just gave you my honest opinion
Re: Air, hot and cold
Nothing to it, plenty of solutions here, you just have to look.
I forgot to add that I got to “heater valve” after searching “hot, cold,” just progression.

I put 'heater valve' in search and came up with these threads.
Your answer lies here. CLICK

Re: Air, hot and cold
The part came in yesterday, when I looked at it I said a few dirty words, because it was not the right one. The new one had all three hose connections coming out on the same side, where the crossfire part has the intake on one side and the outlet on the other. I looked to see if I could re-route the hose and No. As I was thinking about what I could do it occurred to mt to just take the guts out and swap them, so that's what I did, and it works fine now.
Again thanks to George for your valuable help in diagnosing and finding the part.
I have had this car since June 2012, it has 52000 miles and this is the first real problem. We have gotten along real well.
