Blower Motor Issues.. Can't find problem
I drive a 2001 Sephia, manual trans, with 130,000 miles. Lately I've been having issues with my heat/ac working. When I try to turn it on, no air comes out at all! It doesn't work on any speed I put it at, the horsepower is decreased as if it were working... but the only air that comes out of the vents is the air I can SLIGHTLY get while the car is moving. Yesterday, I checked all of my fuses, they worked. Wasn't sure how to check the BLOWER relay, so I switched it with another relay and the problem still occured. Then I took both the blower motor AND the resistor out and hooked the motor to a battery to see if it was working and it was. Wasn't sure how to test the resistor so I tested it with a voltometer and picked up a reading. After putting EVERYTHING back in, I checked the fuses one last time and noticed that I had a 30amp mini fuse in my blower motor section. Owner's Manual says it should be 25. I just kept it in becuase I couldn't find a 25.. It worked fine for the rest of the night. The next morning, It worked when I started my car (I believe it was on speed 2) and I turned it off because it was cold... then later down the road tried again and no air came out at all again. ALL THAT WORK FOR NOTHING?! Any ideas?
