Can anyone post pictures of the HVAC assembly and wiring diagram? I need to see the in dash part, pretty sure I have a bad blend door. Last summer ac worked great, heat worked good this winter. However it was either full ac or full heat(temperature). When switching back to cool it would take several minutes, I believe that was the time for the heater core to cool off after the coolant flow was stopped.
This week it's been warm enough for AC however all I get is ambient temperature air. Compressore is running etc. The sleeper blows A/C temperature air. I believe my blend door doesn't work. I don't have much HVAC experience though.
Would be a plus if you had the sleeper diagrams to as it doesn't switch to heat(pretty sure it the valve in the coolant line stuck shut)
Going to attempt to take it apart tomorrow, have had the glove box and lower panel out before but couldn't see how the rest came apart
