Author Topic: Aux fan resistor (Read 4055 times)

So I'm taking the entire front of the car apart today since I found out the aux fan resistor is dead. It's so much easier to move the radiator, condenser and AFM housing than to work behind the bumper.

Do I pay the $30 at BMA or does anyone have a clever hack? It's an 85 watt 0.5 ohm unit. Radio Shack has 10watt 0.47 ceramics, but I'd need nine to make the proper spec.

It's neater and only slightly more expensive to get the OEM part.

Anyone have experience with the parts? Which is better, the Bosch or the Magna?

Remove the resistor and hotwire the 2 power wires together. You'll have high speed whenever the low speed is triggered. Win on all fronts.

I thought of that, but I like the low speed for a/c. I prefer the two speed system. I was tempted to put another fan in front, in a push/pull setup just to see if I could eliminate the engine fan.

This is the resistor that's attached to the fan, correct? I have my old one that I removed when I did the volvo fan install - you can have it if you want.

You can eliminate both the mechanical and aux fan with one big puller fan. A few of us are using Volvo fans.

Yeah, I know about the Volvo mod. I haven't been over to the yard recently to look for anything fun. I just splice the leads together...temporarily.

JP you have a PM...
