just a tip my 1988 Chevy g20 van i thought the blower was out but the ground wire on the motor is riveted to the housing and worked lose it would work sometimes but i took out the rivet and put a screw in real tight and it fixed it permanent
AutoZone.com will show you a pic.............
remove the blower motor and black box in the engine bay by the blower motor. these evap. cores do leak on the g20s
Open the hood and it is on the left (passenger) side near the coolant reservoir.
how do you fix chevy 20 ac to blow in correct vents
Its made to come out from the bottom.
its the blower motor resistor. its located under the dash on the passenger side. i think i got a new one from napa for $20. it was very simple to change. its tight under there, so its not the easiest thing to get out but its a very simple fix!
motor on bed stays runing
Its located to the left of the blower motor inside the a/c case and can be seen a lot better if you remove the glovebox.........
Looking at the procedure in my 1980 GM service manual and comparing it to my 1984 G20 van, it apears to be simple process. 1983 should be very close. Negative battery cable must be disconnected. Coolant recovery tank and power antenna need to be removed. Blower motor lead wire is disconnected. Blower motor mounting screws (number may vary) are removed. Blower motor and wheel (cage) are removed as an assembly by prying gently on the blower flange. The sealer may be damaged in the process. The wheel can be removed from the motor. Apply new bead of sealer to the entire circumference of the mounting flange of the new motor. Installation is reverse of removal.
