This cold morning my defrost would not come on. Even when auto climate control button was pushed there was no change in fan speed.There is warm heat coming from the vents but very very low. Under hood fuses checked OK, are there other fuse locations on this car or could it be the blower motor. Is it hard to replace.

You have a P/M.

Finally got the blower motor working (not my primary transportation) so I didn't rush the repair. Replaced regulator (K.A.E. - ********), very simple R/R 20min, thanks to the forum information and tech sites. Query, the heat coming from the vents especially defrost doesn't seem to be that hot but there is fairly warm air coming out. Just comparing to my Van..... blasts supper Hot air when on defrost setting.
