Question

2001 saab 95. Heater motor blows but only on defrost. The display shows that it is changing but it doesn't divert from defrost. Fan speed adjusts ok. Where should I go to correct the problem? Also the heat is not hot, like possible the deverter is not going to full hot but blending with cold. Could this be related or do I have another problem?

Answer

Hi, my name is tim, If the dash is showing the correct mode, then the problem lies in the stepper motor in the hvac box, It is not going to the correct position, this is common on these, would you like the procedure for replacement?
