    yeah its a common thing more so for the temp to always blow hotter than it should, which is caused by the heater valve and there is a fix developed by a member on here and available through the club shop. Not caused by electronics.

    Although some people do occasionally experience a wierd occurance of hot and cold switching around and / or hot and cold one side versus the other. I had this once but after switching ignition off and back on it sorted it's self out.

    So over all, not a big problem really but something to check that the a/c blows cold when set to low. This is hard to guage in winter when the outside temp is low. Best to use the car, get all warmed up, and then let it sit parked for a few mins.

    Then start the car, deactivating the a/c, leave temp sety low and you will find the air coming in feels warm due to the heat coming up into the plenum chamber from the exhaust on the LH side. Activate the a/c and if it swiftly gets cold, this should indicate the a/c is working OK.
