    A/C Air Recirculation

    A solution to keep recirculation on by pushing a button even when the defrost mode is on. In other words, a wire to override the defrosters so recirculation can be on in any mode. I thought about closing the diverter and disconnecting power to that air inlet servo however i prefer a electrical...

    Blend door stuck

    The blend door on my 93 is apparently stuck open. There is no heat when you turn the heater on and there is cold air that comes in thru the vents during any drive in cold weather. No water on floor, no overheating. Heater valve has been replaced, just in case and appears to be functioning. Took...

    plastic HVAC controls

    I want to replace my hvac controls. Some of the sliders are very hard to get moving. Also one of the plastic levers is broken. I found what I think is the correct part number. The folks at JP CarParts say it has been discontinued and the controls for a 1990-2004 model can be used. Among other...

    Mudders, I've had a few ask, so I think it warrants its own post - I assume more might have had/have this issue. Maybe this could end up in the FAQ, if enough people post solutions to HVAC problems (with pictures!). PROBLEM: Temperature control for HVAC does not work. Cold is cold, 65 and...
