Gen 2 AC fan won't work at low speeds

[tracyf]

My brother serviced the AC on my wife's 1990 V6 Camry and after he got through the fan will now only work on the two highest speeds and not at all on the two lowest. It is not the end of the world and it does work at the high ones at least (and I did not want to complain when he had helped us out) but I wondered if any of you fine folks on here may have ran into a similar situation and the fix for it. Thanks for any advice!

needs a blower resistor.

Thanks so much. I will check in the manual I downloaded and try to fix this last little thing up for her. Thanks again! Tracy

np, its passenger side floor area, should be a single phillips head holding it in.

http://www.toyotanation.com/forum/t62289.html check here for pics you might have to goto the dealer or make your own resistor pack.... i've pulled 2 resistor packs at the junk yard and they're both bad... it's a very common problem on the gen2 seems like everyone gets it sooner or later

I've been driving around with only high speed on the blower for years now until I read these posts yesterday. I took out the resistor pack and soldered it together in two places but the wire is so stiff and flimsy and there's some rust on the base plate. Anyway, the blower worked on all speeds on the way to and from work. I need lessons in soldering though. My solder kept falling off the join spot. The solder is supposed to contain flux. Is there something you paint on to make the solder stick until it cools?

I called Radio Shack for the resistors in part # 90-903 but they say there's no such part. Same online.

The wire becomes very hot. The solder melts. Replace it with something that will withstand the heat and current. (I've tried Radio Shack 5 watts without success.)

Well, they're not exactly cheap but: if I recall correctly, a new resistor array will run you around $65 at the dealer.

On the other hand, I've had very GOOD luck with scrap yard cars. I have 2 or 3 spares in the basement now.

$65, IMO, is not a bad price for something that's not likely to break again for another 10+ years.

[TBayToyotaBoy]

True enough. Unless you have corrosion at the firewall, and moisture gets into that space where the resistors are. I've seen it on a few scrap yard cars over the years...

I called around Los Angeles today for the gen 2 resistor pack and got a variety of prices. Santa Monica Toyota asks $78, Marina Del Rey Toy $65, and Miller Toyota, Culver City wants $49! These dealers are all within a few miles of each other. I won't buy yet since my solder-job is holding out but will go to Miller if it gives.

interesting.. guess i'm going to have to buy one from culver city toyota then.

It's Miller Toyota in Culver City, just off Venice, West of Robertson and the 10 freeway.

I posted this on another fan-speed thread but want to get the word out. Hope this isn't redundant:
"This auction is for a good fan resistor from a 1991 Truck. This will fit ALL Trucks from 1989 to 1995 using this style of fan resistor and 4Runners from 1990 to 1995."


I bought the above resistor for a 91 truck, thinking I could unsolder these coils and solder them to my '91 Camry DX resistor base. The base is a little different but my wires plug into the truck resistor and the truck one fit into the space on my Camry, though not precisely. The truck one works fine in my car without any new soldering or coil changing. Cost was $2.25 plus $4.00 shipping from E-bay.
