Car Forum / BMW Cars / January 2009Reverse Switch
My '94 325i convertible, manual transmission, does not light the Back Up Lights when Reverse is selected. There's no voltage at the lamp socket, and my schematic says the switch is the problem. Where is the switch mounted? What I'm really interested in is a way to get to the switch without dropping the exhaust system and the heat shield. I'm pretty sure it is the switch, because the lights do work every once in a while, this is a sign of a dirty switch. > My '94 325i convertible, manual transmission, does not light the Back Up > Lights when Reverse is selected.

The switch is on the side or rear of the transmission. It could be the switch or the wiring to the switch, which runs on top of the tranny. The wire often gets kinked/shorted, either where it's zip-tied to the transmission tunnel, or in the bundle on the trunk hinge.

So, are you saying that if I don't want to take the exhaust system down and remove the heat shield just to get to the switch -- and inspect the wires for shorts and breaks, then I have to wait for clutch work -- when this stuff has to be removed anyhow -- before I can get my Back Up Lights working again? I'm disinclined to take the center console out for this, I've worked myself into a tizzy that the switch is bad, and taking the console out is an exercise in futility. >I'm disinclined to take the center console out for this, I've worked myself >into a tizzy that the switch is bad, and taking the console out is an >exercise in futility. Trade it in on an M6. >>I'm disinclined to take the center console out for this, I've worked >>myself >>into a tizzy that the switch is bad, and taking the console out is an >>exercise in futility. > > Trade it in on an M6. Replace a perfectly good car that needs a $15 part with a new car that costs more than 40,000 times that? No thanks. >>>I'm disinclined to take the center console out for this, I've worked >>>myself [quoted text clipped - 7 lines] > >No thanks.

You should be able to reach things from underneath without removing the exhaust system. I could on my '91 525i.

I could on my '91 525i. Yup, I replaced the switch on my '92 535. Didn't take many minutes. To verify that the switch is faulty, short circuit the wires going to it (with the ign. on) and the lights should come on. > FloydR Ulf |
