Hey guys, I have a problem with my blower motor. I have a 5 position switch in a 1984 pickup 4wd 22r dlx. One postion is off and the others are blower motor speeds. Low, med. low, med. high, and high. When the switch is in the 2 lowest modes, the blower does not operate. When it is in the two highest modes, it blows air with no problem. I did try a new switch and come to find out that is not the problem. i find it hard to believe it is the blower motor since it does work on the two high speeds. Any ideas? Thanks!
