The blower motor only works on high speed, and only when truck is in 2wd (electric shift), when the 4-hi button is pressed, the blower motor shuts off, and the 4wd light blinks. You can hear the encoder motor shift the t-case, but the light only blinks. Also the related fuses for the blower motor and hvac, in the i/p fuse box, lose power when trying to shift into 4wd. I have disconnected all components of the blower motor system and the t-case indicators still flash, also unplugged all components of the 4wd system and the blower motor still only works on high speed. Have you ever seen something similar?
ps. Mileage is supposed to say 300,000 but there isnt enough character space in the box
