I'm sorry the Tech you requested was unavailable to assist you today. It appears that Tech is currently "Offline". Now that his 15 minute "request lock" has expired, hopefully I can be of some assistance in his place...
-Does this vehicle have Auto Temp Control?
Great, thought so. This has been an extremely common problem on the Auto Temp Systems. The problem is going to be the Blower Motor Control Processor. It's located under the passenger's side dash, mounted near the blower motor (#2 in THIS IMAGE). Inspect the electrical connector and wire harness for any loose, broken or damaged wires. If the visual inspection checks ok, replacing the processor should solve the problem. Very common.
