|
|
So my fan would not work yesterday morning. I changed the burnt fuse, but when I turn it on nothing happens except the fuse blows if I leave it on. It worked fine the day before other than the chirping that has been there since I got the van. Are there any relays or easily accessible things to check or do I need to pull the dash and check the blower? _________________ 1987 Westy |

It's most likely a bad blower motor. However, make sure to use a 20A fuse. Some use 15A (even Bentley makes this mistake, 97.102, cf 97.116) and they will blow whatever state your motor is in. |

It's shot, change it before you melt you fuse box, and Ignition switch. |

Mine was shot, before I could change it, a traveling friend turned on the fan for heat while I was in 7/11 getting coffee. When I came out with my coffee, my friend was out of the van and smoke was rolling out of the heater vents. Got it turned off in time, no other damage, thankfully. Changed out the blower motor the next weekend! |

Same happened to my blower motor this week after a history of squeaking. Now the fuse blows and I guess I need to replace the blower motor.
Does this motor happen to be the same motor as the one under the rear bench? I'm asking because I have removed the whole heater unit - perhaps I can reuse the motor for the front heater unit. Thanks |

No, the dash fan is different than the rear under seat heater fan. The good news is that the dash fan is a common VW part used in many years and models so they don't cost that much to replace. The 86+ passenger vans with A/C have the same fan in the rear ceiling A/C unit. The wire ends vary slightly at times but the fan assemblies interchange pretty easily anyway.

FWIW - my fan would not run & and would blow the fuse if I turned the switch to '1' or '2'. If I flipped it directly to '3' it would start & run and continue to run even if I lowered it to '1'.
I reasoned that it was seized -- but not by much.
Did the 'Mullendore Port' treatment noted in the above links and now it works fine at all speeds.
Not a fix for a blower that is well & truly knackered, but if it is just a bit bound up (and the problem is the rear bearing) that M-Port might spare you some owrk now and let you address it sometime in the future, perhaps when the dash is out for something else (or perhaps never). |

My blower does not work. After plodding thru the two mentionned links, I think I'll wait until I take the dash apart. Currently run a 2 speed 12 V fan across the windshield. _________________ '09 2.5L Jetta 5 cylinder, 5 spd, super turbo, see thread in H2O Cooled Jetta, etc...

I just replaced mine. It really wasn't that hard. I just used the Bentley and Ben's web site. There is one diagram (in the Bentley)that says to remove screws above the glove compartment and I simply could not find the screws it was referring to. _________________ 1987 Westy |
