Blower motor for heater and a/c does not work. I removed it and checked with battery outside vehicle-OK. Replaced blower motor relay in fuse box passenger side-OK. Replaced blower motor resistor-OK. Checked relay for fansetting switch-clicked-OK. What else is there?
I had the same problem, replace, replace, replace. Check, check and recheck. What I found was the blower motor resistor, located in the blower squirrel cage area, two prongs and a curly wire, was bad. Took the new one back, (it ohmed out okay, continuity ok, all ok!) replaced it with another, and Bingo, problem solved. Frustrating to say the least. After two relays and a blower switch, and test, test and retest. It was a faulty resistor. Made in Mexico. And no guarentee, even though new, it works. Trial and error. Even the dealer parts are Honcho en Mexico. Thanks NAFTA. You gonna make us all welfare babies.
Its
faulty blower motor resistor. The low and medium speed on blower motor is
controlled by resistor and its actual speed is high. So because resistor is not
working, blower motors actual speed which is high is working.
It
can be faulty blower motor or faulty blower motor resistor. Get the blower
motor inspected. If it's faulty it has to be replaced.

An inoperative blower motor could be caused by the following:
* Blown fuse(s). The fuse should be replaced. There may be both a
LOW BLOWER and HIGH BLOWER fuse. Some models may also call it the HVAC
fuse. Even the RADIO fuse is used in some applications. Check them all.
If a fuse is blown there may be a short to ground in one of the power
supply circuits.
* Open Circuit. Check the circuit between the ignition switch and
the blower motor, and the blower motor ground circuit. Repair as
necessary.
* Faulty blower switch. A faulty blower switch should be replaced.
* Most heater blower circuits also include a blower motor relay
(look in the underdash convenience center), as well as a blow motor
resistor. These items should be checked especially if the blower runs in
one or two speeds, but not all speeds selected.
