blower motor resistor? (1 Viewer)

[71-CRUISER]

I am working on a 73 FJ55 (see Ultimate 55) and I am in need of a blower motor resistor. The part is screwed to the underside of the blower housing in the engine bay and has one plug into the truck harness.

I just spoke w/ Spector and they said that they didnt have any and I know Toyota is also out. However they did say that it could be replaced w/ a "8oh 10watt power resistor". I was thinking that i would need 2 seperate resistors since there are 2 coils on the factory resistor.

Does anyone have any experience with modifying the stock resistor or have a good one that they are willing to sell.

Thanks.

I was going to do that and I may have, I can't quite remember if I found an OEM resistor or not (it was 4-5 years ago). If you do, put the resistors in the air stream to keep them cool. Yes, you'd need two resistors. The switch sends power direct to the motor for high speed, through one resistor for medium speed and through both for low speed.

Those resistors will be probably 2" long and 1/2" diameter!

mine only has 2 speeds, high and low??

there was a thread maybe a year ago in the 40 tech section about a replacement/swap maybe search there

If it's only two speeds then you'd need only one resistor for low speed! I can't recall off hand how many speeds are on the '76 FJ55 blower.

the truck is a 73 and it has 3 speeds. there are 2 seperate coils on the resistor, one large and one smaller.

Because one coil is larger and one is smaller (I remember that now), if you use two equally sized resistors the speed may not be exactly the same as stock but who cares. Unless you have A/C it's not really an issue.

If one of the coils is still good you could measure resistance across it and let us know both resistance and whether it is the low or medium coil. Remember that on low speed power goes through BOTH the low AND the medium speed resistors.

OK so there is a big coil and a coil. as you can see the large coil is still intact and measures 1.2ohms across the 2 posts. the smaller coil was broken so i twisted the broken ends together and it measures 1.2 ohms across the posts. I am going to buy a small resistor and just sodder it in place.
