You have a relay located behind the glove box once removed to the left and you also have a blower resister that controls the speeds located on the passengers side in the blower motor housing..............
fan speed control switch is bad. Replace it as long as the other speeds work fine.
The 1996 GMC half ton pickup truck heater core can be removed by removing the heater core retaining bolts. Remove the heater core water lines. Reverse the process to install the new heater core.
I have a 94 gmc seirra and the fan speed is controled by relays behind the glove compartment just pull the inside of the glove box it is mounted above the heater
remove the glove box and there are three relays one is for the control door
No, it only has one fuel pump relay.
On the 1996 GMC Jimmy, it is in the Glove compartment. There are 3 relays in there. May not be the sme on the 1994 but, this may be a good plave to look.
