So, I'm new here, have searched other threads before posting but no luck. I Seville has had an ongoing problem with the A/C blower, FRONT ONLY. It basically works when it wants to. When it works, everything works fine, blows cold, speed controls are fine. When is DOESN'T WORK, air comes thru the vents only on the highway and comes thru cold. Tricky part, passenger side and right vent in the middle comes thru cold, left vent, driver vent and leg vents come thru hot. Rear A/C works fine and cold. Any help would be very appreciated.

Re: 2002 SLS front blower not blowing
Study and use the proper car/year group instructions in the sticky post just above this thread - "How to pull codes" - Your car has a built-in code reader/scanner/memory and it will tell you if there's anything wrong with most of the HVAC blower/door/temperature control circuits. The system uses the 3 DIC control buttons just right of the instrument panel. When you enter diagnostics the buttons change function - study the sticky.
Get any stored codes, and then use the link to OBD-II codes in the sticky. Decipher it all and post it here.
