I have a 95 S10 Blazer and the heater blower wont come on.. It wouldnt last night then after driving a little bit it came on this morning it worked fine, But now it wont come on at all any one have any ideas??

check the fuse and make sure there is a clean seat for the connection, then check under the hood and make sure the wires going to the blower are on tight and are clean

Disconnect the termial under the hood and clean the contacts, add terminal goo (correct term unknown) and should be O.K. I have had the same problem inermittianly it goes off and after cleaning and goo it has been fine....

that terminal goo would be called dielctric grease

Thanks guys I will try that in the morning and give you an update tomorrow. Gotta have the heat its neg 10 here In Rapid City South Dakota...

The other issue is the fan may simply be dead... I recently had to change mine out. Squealed like crazy when it ran, but it had a flat spot the the brushes would hit and the only way to get it to start would be to hit a pothole or what not.
