Where is my MFU?

[AndyThoma]

I have a 95 D1 and can't find the Multi Function Unit for the life of me. Where is it? All the places RAVE and others say to look, I still can't find it.

My neutral sounder is always going off when the truck is in any drive gear. Everything related to that sounder works, CDL, gear selector, ignition lock, but the sounder thinks its in neutral. So to kill the sounder I pulled fuse 13 and it stopped the sounder. Unfortunately now my intermittant wipers and rear defroster no longer work. I think its the MFU and I have a replacement, but can't find it on my truck. Any ideas?

I'd have to go look to be sure, but isn't it behind the glove compartment where the window ECU is?

The MFU is down in the Driver side foot well BEHIND the fuse block.

have you check the gear selector switches first???

that should fix the false alarm your "sounder" is giving you...

'Gear selector switches', the park neutral switch or another one? I replaced the park neutral one already, plus my CDL works fine.

Is this what I'm looking for?

on my 96, the MFu is located on the passenger side of the engine compartment next to the charcole canister

Brad i think you're talking about your ECU

Location

Brad is correct...On all 96 units up the MFU was on the passenger wheel well by the ECU. 94-95 units were inside the truck behind the fuse panel.

Okay, I pulled the fuse panel and the styrofoam thing from under the steering column and no multi function unit. Nothing was under my fuse box at all. I know where the mfu is at for a 98/99 d1, and its not there. Under the side kick panels, nothing. Under the glove box, afraid nothing like what's in the picture above. My truck was manufactured 12/94, where they located somewhere else in 94? Could I just not have one, if so what controls that damn sounder?

anyone have an idea?

Andy,

are you sure you checked all of the switches in your gear shift selector??? seems to me that would be the root of the problem...
