98 Bravada Smart Trac

[Chris Stewart]

Thanks for the update! I guess those multifunction switch's are not real durable.

Replaced the switch today and seems to have solved the problem, I know I said that before but lets hope I really got it this time!

so does removing that AWD fuse hurt anything. like does it wear out seals or cv axles prematurely? what about OBD II, does it effect that and finally will it increase fuel econ? and performance

[CutlassOlds88]

removing the fuse won't hurt anything. it won't affect performance or fuel economy because the 98 bravada is rear wheel drive anyway.

im sorry, i forgot to mention that i have a 96 bravada

[CutlassOlds88]

the 96 bravada doesn't have an electronic transfer case. you'll have to remove the front driveshaft to run it in 2wd. that probably will increase the gas mileage.

I'm not sure everything will be ok running the older style viscous clutch transfer case without the front drive shaft connected. The cutaway drawings and illustrations show the gears & shafts in what looks like a planetary type arrangement. Except for the limited amount drag from the viscous clutch, taking the front driveshaft loose leaves the power transfer "open-ended".

I had the issue in a 99 Bravada. Went from the turn signal sounding like it was on, to a buzzing. It would go away on occasion and then come back. When I used the turn signal or hit the brakes, it went away. It was the Multifunction Switch. AC Delco will run you around $175+ to purchase plus installation if that is it.

Thanks for the info.
