I sold my 06 HSE for a project car. I bought a 99 HSE with 100k on it. It appears to be solid mechanically, but there is one issue. The climate control only blows hot air. The Book with Exclamation mark are lit up on the climate control system. The AC compressor does come on when you set the CC panel to low, so I think it is most likely a blend motor issue. I wont pay the dealership 1000 to replace the parts, so I will do it myself. Is there anything else I should check before I go into my dash and replace the blend motors? Also, any advice on how to replace the motors would be helpful.
