Hey Guys! I have a 99.5 Audi A4 1.8T Quattro and I need to fix this problem as soon as possible. The issue is that my power door locks just doesn't work at all. I check the fuses and all of them are just fine, just wondering what else can I check beside the code reader(because I'm going to use it tomorrow). I have to lock everything manually from the inside to make shure no ones steal my Sick B5 LOL. Also, I just install an Alpine amp a couple of days ago, do you think when i did the wiring, I screwed up one of the wires or something? or maybe something else.

Any Advice is appreciated! Thanks for taking the time to read!

 

The door locks are operated by a vacuum pump in the trunk. Poke around where your amp is installed and make sure you didn't accidently disconnect any wires.

 

Can you please tell me where the actually check? I mounted the amp on the right rear passenger seat(bolted on back) with the extra wiring under the rear seats. I just wanna make shure what i need to look for. Pics? or what color wires is it? or where is it usually located? So i can see if its actually the wire unplug.

THANKS!!!

 

any thing please?

 

It's in the right rear of your trunk underneath the trim.
