New owner of a 92 325i with a few gremlins but generally good condition. Right now I need to find out about 2 wires beside the battery positive block under the hood. There are 2 wires with fuse holders in line on the wires and there are no fuses in them right now...any idea what these wires are or control or if important what fuses are supposed to be in them? If needed I can provide a pic... one of them has a second wire that grounds om the chassis right in the same area.
I have both manuals haynes(crap) and bentley but am having trouble tracking this wire prob.
A few of the other probs that have me finding this as well as other little wire probs is that the A/C compressor is not turning on so seems like someone has disconnected it.
I am going to fix all the probs if it kills me as I really like the E36.
These really look stock though guess I will post a pic...no aftermarket stereo that I can tell, as orig radio was there (til last week hehe)...
K so any ideas or old threads on troubleshppting A/C not turning on? I am pouring through manuals and wiring diagrams etc. but am sure ther must be a write up or someone who has gone through similar no power to compressor etc.
I will provide more details as I dig in though as always fix everything presented to me eventually.
and finally down in bottom of the previous pics in the hole you can see a wire out of the firewaall that is cut off wiith a yellow and red wire in it...look close and thanks for any help on these everyone
The location and wire colors look kinda like an alarm system siren plug to me. The other two fuse holders look like ground wires if they're spliced into that one running off to the right, but I can't tell without removing the electrical tape and seeing another picture. Did the car have an alarm before and maybe somebody yanked it out?
Maybe your A/C is out of gas...
Some cars come out with a pressure switch that only allows the A/C clutch to operate when the pressure is at the correct levels..
saves your compressor running dry could be a good thing till you find the problem..
if you have a test light connect it to either side of the fuse holder, if it glows brite something large is connected to it,
some telecommunication trades people use a f-Set for tracing cables, connect one end of the signal injector to chassis ground and the other to the wire in question.. the with the remote locator's you can start (sniffing) around the cars wiring loom following the wire by sound.
My guess would be that the fuse holders are for a mobile phone hands free unit....B) or special services that are to be connected at all times .......
