havac stuff need help
Vents always blow out cool air no matter what I do, I cant even get it to blow out warm air from the engine. The temperature blending clip was broken so I ordered a new one, this didnt help though.. still blows cool air. Any ideas?

Is the AC clutch always engaged? Disconnect it once and see if that changes anything. If it does you'll need to trace the wiring back and figure out if you have a bad switch or a problem with the wiring.

It does sound like the clutch is always engaged. Thats a bad thing because when the fan isnt blowing itll screw the system up by over icing it. Could be the switch, the clutch, a relay, bad grounds. Its hard to say...but it does sound electrical not relating to the ducting.

That happened to me. It was the relay.... Relay #3 in my early car. Probably not the same.
