Hi 8ers,
My HVAC is playing up, I'm getting hot air from some vents all the time (even with the driver temp on max cool). I know this stinks of heater control valves but I replaced these a few years back so I'm thinking it's something else (i've ordered a 12v probe that I'll use to rule out the valves). I connected DIS (still blows me away how much info that gives for a 1991 car) and ran some diagnostics. There was an error regarding ambient temp sensor, and when I saw the values returned by the various sensors the ambient sensor showed 0c. According to the HVAC manual this is the default when the sensor is broken. Whether this is the root cause of the hot air or not I ought to get it sorted so does anyone know where this sensor hangs out? I can't find it on realoem.
I know there is an ambient temp sensor in the air intake in front of the passenger front wheel, but I think that's for engine management or just for the MID??
I'm really enjoying my car now and am driving it every week. There are a few fairly significant problems that I need to solve to make it more liveable but the heater being jammed on is right up there so help me out 8er heroes
