2005 Chevrolet Trailblazer LS 4.2L Blower motor electronic resistor block
Vehicle has been back three times now with only high speed working. Each time I have found diode on control module to have failed. Replace module and find all to work normally. I am looking for sugestions as to what to test to see what is damaging these module...
