SW Indiana | Have a 2007 International truck that the blower fan only operates on high (position 4), 1, 2, 3 is same as off. Changed switch with no help. Looked in the breaker box behind the glove box and didn't see anything. There is a relay for high fan, when I pull it out the fan stops on high. There is also a relay for medium fan, pulled it out and put in a different relay but didn't help. Any ideas, Thanks | |
