fan controller module

[jungle]

looking for this fan controller module...it is found on my 94 jetta, and pretty much any 92~early 95's. p/n 1h0-919-506a

mk2 uses same fan control as mk3?

^^^

No, mk2 uses a relay.

I know I have two, just need to find them. I'll check in the morning.

[20VT]

it just said 92 so I assumed mk2.

I had a 95 burn down due to a faulty one of these. I strongly suggest replacing it at any cost. :tear:

[jungle]

Does anyone have one to sell or let me borrow?

I got a new one from Ebay, and I have no high speed fan, plus the low speed fan doesn't shut off when the car is turned off. I got another new one, and it does the same thing. So I don't know if I received two faulty brand new ones or my car is goofy.

So I'd really like to try these new ones in another car, or try a known working one. This model was found in 92~94, golf, jetta, passat, & corrado.

Hey Aaron,
Maybe you have already seen this page but it might help
http://faculty.ccp.edu/faculty/dreed...work/index.htm

You could have a faulty radiator temp switch, if it is bad (shorted out) it could cause the fans to run even when the car is off

This is from that web page -

IF THE COOLING FANS DO NOT WORK:

Well, here's a fast test. The Fan should Should have these colored wires:

Brown (ground)
Red/White (low)
Red/Gray (high)

Locate the fan sensor (drivers side, near headlight, in rad..) its a 3 wire sensor.
It should have these wires:

Red +12V from fuse 19, 30A under dash
Red/White (low speed trigger)
Red/Yellow (high speed trigger)

Check All fuses under dash. 19, 6 and 4 are key as well as a brass colored bar on the coolant module.
Anyhow. On the fan sensor, unplug it, and jump with a paper clip:

RED to Red/White (fan should come on low speed)

Unplug it. and then;

RED to Red/Yellow. (fan should work on high speed)

IF THE FAN RUNS REPLACE THE SENSOR IN THE RADIATOR.

---

IF the fan DOES NOT come on jump power TO THE FAN.

IF THE FAN RUNS when jumped directly to power:

Replace FCM.

Thanks sean, i have actually been down that very same trouble shooting path, and am at the "Replace FCM" step.

....the high speed fan ONLY works when supplying 12v directly to the fan; jumping the sensor gets only low speed.

[Seannabend]

have you checked the condition of the radiator temp switch though?
if that has shorted out it could be the cause of the fan running when the car turns off

I wish I could help more but the FCM for my MKIV is different
good luck

Does your fcm have 10 or 8 pins on the little connection? I have 3 (10 pin version) that you can have for shipping to you. If they work great if not toss them in the trash.

hey Arron,
Give me a call I have the same problem but mine only comes on high speed when i jumper the thermo switch in the radiator. I have the FCM that i got from you at the swap meet it didn't change my problem. I left it in there, can get it back to you if you need.
