Audi Repair Questions? Ask a Mechanic for Answers ASAP
Hello there, I can help. First, what engine do you have the 2.7L or the 4.2L?
Ok give me a sec to pull up the diagram
Ok I got it pulled up. First, how did you check the fuses?
Ok, are there fuses under the hood and in the car?
Alright, so the HVAC control doesn't power up? The car wont come out of park? Air suspension inop? Yes 2004 audi all road
Are you able to work on it now or just want some test instructions?
Well that's a good thing. Sounds like a partial power lose. I am going to give you some areas I want you to test for power. The HVAC control head has two 12v power supplies.
When you get time, I want you to test these wires on the HVAC control head connector. #1-Black/red(hot in run/start) and then #2-white/yellow(hot with load reduction relay energized).
Mainly I need to know if you have power on the Black/red wire.
Lets concentrate on one system at a time. I picked the HVAC control head because it is probably easiest to get to.
Can you do the task? Or would you rather start somewhere else.
Ok excellent. Also check for continuity to ground on the two brown wires. They are the grounds for the circuits involved.
I will keep this as simple as possible for you so if don't understand at anytime please say something! Would you like more troubleshooting tests for the other downed systems?
When you say wires got caught in the fan do you mean the radiator fan? Did those wires go to the a/c pressure switch?
Have you looked real hard for a fuse box under the hood?
I am sorry I think I gave you the wrong vehicle wiring info. Is your car a GL or GLS?
Nope, I gave you the right info. Just got confuse there for a second. Wanted to make sure! Ok so do you want the wire test colors for the next down system?
Ok how about I email it to you? Would that be ok for you?
Anytime, anytime! Have a good night!
I haven't heard back from you, do you still need help with this issue? Did you get the email on the test procedures? Have you had a chance to do them?
If you no longer need help, please rate me and close this ticket. Thank you.
