Title: Omega 2.5TD year 2000 - A/C panel malfunction
Post by: DeskJockey on 03 November 2013, 12:21:23

Hi all,

I wrongly posted this issue in the introduction forum so I'm re-posting here. Hopefully someone may have seen this before and could help:

The whole a/c panel goes dark without notice, exactly when the car rolls to a stop. This happens when coasting or braking to a stop (engine idling). The button lights, temperature settings and other symbols go out and the heating system stops responding.
After driving off again, the system can be reset: press "off" and "auto" and all is well again until the next stop.

All of the other systems seem fine.

The only solution to the problem I can see is to drive through stops signs and red lights without stopping but I'm not sure the road police will agree to the cure.

Cheers

DJ

Sounds like a loose plug/trapped wire :y

I've had this car for 3 years without anyone tampering with it, me less than anyone else, as I stay away from electrical wizardry.

My technical knowledge is limited to changing the engine oil and filter every year and the other odd jobs (new wipers, stuff like that)...

I even had the Opel people do the auto gearbox oil/filter change for me.

In that case it may be wiser for you to entrust this to an auto electrician :-\ :-\ :-\

I'll try disconnecting the battery and leave it to sit cold for a while to sort of reset the control modules. Doing that and checking the fuse connections may have an effect...

If that fails I'll head for Opel Service's loving arms for a major ca$hectomy

I'm sure there are independent auto-electricians in France who will be cheaper, and probably even know what they are doing! :y

Since I use my scooter most of the time the Omega has sat with its battery disconnected until this weekend.

I used the car today. The a/c system is dead (as in: no lights, no reaction to the on/off buttons).

Post-mortem revealed that the fuse is blown...
