Temp control not working in Climate Control
My Navigator has the Climate Control system and just the other day my temp control stopped working. No matter what temp I set it to, it just blows hot air. It seems to be stuck on the highest as it's pretty hot when it blows out any of the vents. All other parts of the Climat Control unit seem to work fine. Any ideas what it could be?

All Navigators have electronically control HVAC's (EATC) right?
The problem could be caused by things such as (1) Actuator is broken, (2) Temp blend door is broken, (3) the "sniffer" hose has become disconnected, etc.
The EATC system may have built in diagnostics. You'll have to search the Internet about how to get to them and what the codes mean.
