Alarm and D locks not working
 

Hello,

I want to thank everyone for their contributions and am hoping to get a little help with a pending issue.

BACKSTORY:
took my car in to fix AC(its hot right now in San Antonio). Got car back and AC worked great!. Stereo did not work and trunk no longer opens. take it back to have these issues resolved. get it back and now I have no locks or car alarm.

I think I have it narrowed done(hopefully). The fuses are intact. However I did notice that there are not 2 wires coming off each fuse. Specifically the Alarm fuse and door lock fuse only have the power cable attached. Electrical engineering is not my specialty and my limited understanding is that the circuit needs to be completed. ie negative /ground wire.

Am I missing something? is it grounded in someother way I am unaware of?

please advise

thank you

The fusebox itself might be the ground. I don't know that for a fact, but it would simplify production I imagine. Best bet is to check a wiring diagram (foxed.ca, for example).

Did they fix the trunk and stereo or none of the 4 things work now? Suspect they might have played with the relays for those systems and swapped them around, moving the problem relay to a different circuit.

Otherwise I would trace what all those systems have in common (e.g. room fuse, or some common relay) using a wiring diagram and start your troubleshooting there

Thanks for the tip.
I did not have them fix the stereo. The service manager suggested a better method for connecting wires then what I was using. Since an upgrade was now on the table I would not expect /request the repair be made knowing I would redo it anyway.
Its working now and simply required the replacement of the remote signal wire. for reasons beyond my understanding they cut it in multiple locations.

I did not have them repair the trunk. They showed me the broken piece that keeps it from working; 14 year old plastic. It's time was up and am not going to make someone pay for something they didn't cause.

All petroleum based products are slated for replacement at this time.

There is a guy named Rob Dahm, owns a shop out here in Texas that built himself a 4 rotor AWD beast with some great DIY videos on youtube for rewiring a vehicle. I think it's time to do that.
