2003 Chevrolet Tahoe heat/ac fan not working.
So my 2003 Chevrolet Tahoe with 154,000 miles has issue with blowing heat and or a/c. For awhile, its only worked on speeds 3-5. Now, only working on speed 5. 1-4, not working at all. Is this an issue...

Replace the blower motor too! It is the high resistance of the blower that causes early resistor failures.
