2001 Jetta fan problem - overheat

What was VW going to do for $1000.00!!!

No the battery doesn't need to come out. Did you ask the dealer what parts were needed for the repair? Did you ask the dealer if they would contact the VW area rep for possible assistance as you may get VW to pay for the parts or a "%" of the parts?

The fans are controled by a "fan control module". This isn't something you can scan with a VAG COM or such. The way I've always tested them is to swap 'em out and see if that solves the problems. If you get under the car and look up as if you were trying to see the bottom of the battery, you will see a black box with a white bottom that has 2 wiring harness plugged up to it. One of harness will have 4 or 5-ish large wires, and the other connector will have 10 or 14 wires. I've just been unplugging the unit that is bolted to the car and stuffing one of my test modules in it's place.

However, you menti> Hi Group,

I am in the process of this. I did find paperwork that indicates the fan oscillates when the A/C is on, and this was noted in a service while under warranty. The service department could not duplicate the problem, so nothing fixed at that time. Hoping this will be all that's needed.

But I will ask about contacting the area rep - a good idea. and I will get a list if what parts are needed when I pick up the car - will leave it at the dealers until Monday when I talk to them about the past reported fan problem.

thanks

Last month we did 4 sets of fans with the internal low speed resistor bad! Pencilneck, you make it to Phaeton class yet? I did and just got back. Check my site for pictures...

Thanks for the info. If I take the car back, (see post above this one) I will check this out as you indicate. I know shorting 2 pins in this connector should make the fans work at low, and I think high (another 2 pins) - but hoping the previous service and fan notation will let them correct the problem under warranty.

I assume this resistor is a high wattage type to basically voltage divide the 12 volts (down to maybe 6v) so the fan will run at a lower speed. Is the resistor one I can replace if I remove a circuit board?

thanks for any info.

Never had the fan apart, and if you did don't think the resistor can be found separately. I do know the fan near the battery is about $200 alone and the other should be less. If it's a 2.0l you should be able to do them in about 2-3 hours because warranty time is about 1.5 hours without any diag time. If your dealer did all the service on your car there's a good chance VW might help, especially if you gave the dealer "GOOD" reviews when VW called you after warranty repairs...

Yes, all service done by the dealer.. I have not idea what the fans cost, but if it's a simple fan replacement would much rather pay the $200 and do it myself. I'm planning to talk to the dealer tomorrow. Thanks for all the great info.

I'm being told BOTH fans do not work at the low speed.. and this is interesting to me.. as I've worked with fans before - the VW solution is to replace both fans.

Woodchuck, I hope you read this. I find it difficult to believe BOTH fans would fail at low speed, yet continue to work at normal speeds??? This indicates to me the fan motors are fine and the control circuit providing the low speed is not putting out the correct voltage.

Let's assume the low speed of the fan runs at 6V when the A/C is pressed 'on'. And the fan kicks into high (12V) when the water temp reached some preset temp. The High works fine. How could BOTH fans fail on the low speed?

Any insight to the voltages used to run the fans at low speed would be appreciated.

VW dealer is indicating that the past reported fan problem at 9600 miles is to long ago to cover under warranty.. which sounds strange to me also.. it was reported that the fans were not working correct, and nothing was found wrong at the time.

thanks
