In my 1990 Audi 200 Turbo in when the climate control system is in the ECON, Bi-Lev, Auto, or Def modes the blower motor sometimes works and sometimes doesn't regardless of the mode or the fan speed (hi or lo). Occasionally, when I make a right hand turn, the blower motor will suddenly come on and will usually stay on until I hit a bump, at which point it will go off. I put the A/C Control Head in diagnostic mode (by hitting the outside temp button and the off button) and checked channel 7. It indicated that everything was OK (compressor was on, etc.). Both interior temperature sensors channels indicated the correct temperature. My questions: 1. What are the common failure points indicative of the above symtoms? 2. Would a "Going, going, gone!" blower motor exhibit these symtoms? 3. Could it be a loose connection or wire, and if so, where are the likely places to look for these loose connections? 4. Could this be a faulty blower control unit, and if so, where is this unit located? Any help is appreciated.
