get a new heater switch
johnny frank
I have a 1996 Astro van and I'm having trouble too. My fan motor sticks. It has for a while. Its not the heater but the fan that has draged. I can get out and pound on the casing, and sometimes it starts up.
Look under the hood for the radiator fan. The fan is mounted to the pulley at the front of the water pump.
check heater fan to see if it is working.
.035" Check other tuning information as listed on the radiator fan shroud.
If the heater fan is not blowing on a 2001 Chevy S10 Pickup, it is possible that the fuse needs replacing. It is also possible that debris is interfering with the operation of the fan. Could also be, a faulty fan motor, a faulty fan motor speed resistor, a faulty fan motor switch,
i own a 2001 Chevy venture warner bro. edition. and the rear air blows hot while the air is on up front.. i had it checked out and the rear has no ac its just a fan for the back..go figure. my customized Chevy express full size van does the same thing
should be in underhood fuse box!
i have a 2003 chev astro van and need to replace the blower fan
Sounds like the relay is bad.
It could be electical like a fuse, but I had a problem on my 2000 Astro that was caused by a rubber vaccuum line that was split. I replaced it for about 2 bucks and it corrected the problem. Hope this helps
They are replaced as a complete unit, there are special tools(a large thin wrench) that you can borrow from an auto parts store.
