No matter what I try, I can not get the heater to run cold! No matter where I put the heater control dial, it still blows hot.

So far I have changed the control valve (new) and the control panel complete with a different circuit board but still no joy.

No matter where I place the dial, I still get 12 volts at the valve and the valve is held open.

I know it's not a zed, it's just a run around for my wife, but can anyone shed some light please.

 

To add, my wife is partially disabled and due to her medication, she constantly suffers from high temperatures.

The last she needs is the heater stuck on hot.

 

Any help would be very much appreciated.

 

Cheers, Dave.

I used to work for Fraud and we sold hundreds of heater valves, but you say you've changed that. Bypass the matrix, that'll do for now lol ;)

Yeah. My fiesta had the same problem, but changing the control valve sorted it. Not covered by the ford warranty tho, surprise, surprise.

Yeah I had the same problem with my 2000 zetec s, had to replace the heater control valve about 3 times, not part of high standard!! I think they used a low grade plastic that melted easily with a tiny bit of heat that would make the control valve stick either fully on hot, or fully on cold. pretty easy fix though, just a matter of draining the coolant from the bottom of the radiator, and removing the hoses to the control valve, then changing it, fit the hoses back and re-filling the coolant

Snap, had a fiesta that only blew hot and it was because previous owner had bypassed it already. 5 min job to sort, I just used an ebay one and never had any other issues during the couple of years I had it.

I think this is SPAM !
