1999 Chevy Tahoe Limited
V-8 gas
GM tech = jk
question = We just had our first real cold snap. My heater fan quit.
It had previously given no problem. When I attempt to turn it on now a
clicking sound is heard but the fan really never kicks in on any
speed. The sound never changes and no air flow is noted.
I believe the heater fan is located just above the passenger foot area
but want to confirm this and the procedure for removing the fan cover
and fan itself.
I also want to replace the fan relay while working in this area.
Is the relay under the hood or located under the dash near the fan? Is
there more that one relay as well?
Thanks for the help.

Problem with my 2002 Chevy Malibu
3.1
tech = JK
question = My A/C will work when I have it set for fresh air but when I
set it to recirculate I can only run the fan on 1 or it will shut down.
Is there a cabin air filter on this vehicle that may be clogged and
causing this problem.
JK:
I need a little more info.
Do you mean the fan only runs on speed 1, and not any other?
Does the fan run on all speeds, just no airflow?

If in fact it is the blower or resistor, yes the blower is under the rt. side of
the dash. Remove the lower dash panel, and the panel to the rt. of foot
well. It is a little tight getting the motor out. The blower resistor is
accessible through the glove box, is on top of the HVAC case, to the left of
the motor. The HIGH blower relay is next to the resistor.
Be sure and check all fuses before any part replacement to be sure it is
not just a fuse. Underhood fuse block, and dash fuse block.
