Dual heater control valve DCCV went open, if AC compressor is working right. But haven't looked up those codes. Just a guess.

Thanks. Replaced heater control valve 3 weeks ago & things worked good. Now blowing hot air.

If you used an aftermarket heater valve,it may have fizzled on you. OEM is the only way to go. Tasca Ford or Ford Giant.

Not what I wanted to hear but yes I used a Gates replacement. Thanks for the heads up. I'll recheck that replacement part!

I've put 2 after market heater valves in mine over 2 years, last one I put in was oem and so far so good after 1 year.

aftermarkets get chewed up fast! (at least on mine)
