Looks like I've got some electrical problem:

1. No turn signals
2. No blower motor (front or rear)
3. ABS and Airbag light stay illuminated

None of those things share a fuse or relay, but I relocated all fuses and relays hoping to move the problem without luck. I don't have a wiring diagram, so I don't know where to begin!!

If I can't fix it this weekend she says it HAS to go to the shop. We can't be without the van. :(

did any of these start at the same time?

Yes, this all started simultaneously. One day it all worked, the next day, none of it worked!!

Sadly, what they all have in common is the body control module.
The turn signals go through it to turn on the rear lights ( as far as i could tell when glimpsing at the schematics)
The blower motors both go through it as well.
All computers are linked to it through the bus system (inter-controller communications)

I sure wouldn't want to guess one myself without having it properly diagnosed as they can cost a fair bit. But I'm sure leaning towards the Body Control Module. If you want to junkyard one, they're a little tough to remove, under the dash at the driver's feet. 4 large connectors (11mm nuts), 2 smaller ones on top.(clips) 4(?) 10 mm bolts and slides out. Usually the wipers fail as well. Best to have it properly diagnosed.

Damn.

Thanks for the advice. *sigh* I guess I'll have a repair bill to pay.
