Replacing heater blower motor




By unixtool1192 on Dec 23, 2008

" "
I just bought an '84 Toyota pickup, 22R engine. The guy said that the heater blower motor probably needed to be replaced, because it only worked in the low position. The first day, even leaving the switch in Low, the heat would be fine after driving a few miles. Now I get no heat (1 week later). There is no air flow, so I am thinking the blower motor or the switch finally went bad. When changing position of the heater switch, I can here a click in the dash when going from the off position to the low position, but there is still no air flow (with the ducts in any position). so I want to replace the blower motor, but how do I check the switch, and how do I get the dash off?

- Thanks guys for all of the help. I replaced the motor over Christmas (it was really easy) and it works great now.

For anyone wondering how to replace the heater blower motor:
Remove two screws on bottom of front face of glove box
Remove Glove box
Heater is just behind the glove box on the right side (the motor points downward and the fan is in a big round shroud).
Un plug the cable bundles that get in the way of removing the blower moter (the motor will come straight down).
There are three bolts holding the blower assembly in place, remove them and the blower assembly can be removed (pull downward).

The replacement motor I got at Advanced (like $43) was a bidirectional motor, so the leads for the motor were not in a connector like the original motor (no big deal). I hooked the black wire from the new motor up to the connector were the wire with the line on it (from the truck) was and the red wire from the motor to the solid colored wire from the truck (the wires from the motor had leads that you could slide into the connector from the truck). It works great now.

I was hoping that it wasn't the resistor, because then I would have had to wait a couple more days for the resistor (more days with no heat).

Look for the HEATER fuse, under the dash, on the left of the glove box. See if it is blown.

this is not a problem with thw switch or motor. There is a resistor that is mounted inside the dash on the pasenger side that controls the speed of the blwer..these have a tendency to burn up after 10 years or so... replace the resistor, and you will be fine!  http://cgi.ebay.com/ebaymotors/Toyota-Truck-A-C-Heater-Fan-Resistor_W0QQcmdZViewItemQQcategoryZ33548QQihZ016QQitemZ260344846266QQrdZ1QQsspagenameZWDVW#ht_500wt_1230

1984 toyota pickup, runs great but heater blower will not come on; even after turning the selector switch from high to low. Additionally, playing with the switch on day the blower came on but now no-it will not come on. I have checked the fuse (20 amps) and can hear the relay click when the selector switch is moved from high to low.

Help -Could it be the blower or a electrical short?
