Window issues
I’m having problems with my c5 windows not working sometimes. Sometimes when I crank the car they both work. When they don’t work it’s not just one side or the other, it’s both sides. When they do work both sides work. I’ve replaced the driver side control panel for windows, door locks etc. but still having this issue. Anyone know the problem or can offer a solution?
Thanks

I copied this from previous posts, HTH
Most likely the relay to control the window on the Door Control Module has failed. Very common C5 issue. You can either replace the relay yourself (involves unsoldering old relay and soldering new relay) or you can send the DCM to a place that will do the replacement for you.
Here is a link to a thread about the DCM and the relays:

The NEC vertical relay in the pictures is for the window.
If you DIY the relays I would replace ALL of them with the more heavy duty replacements to avoid having to be in there twice. JMHO
If you want to send the box out for repair here is a link to check out:

The most probable cause is a dirty relay contact inside of the Right Door Control Module (RDCM) The relays are known to go bad due to arcing. There have been a few people who have preformed surgery on the DCM's and have replaced the bad relay with good success. Some have just replaced the module. NOTE!! There expensive!!!
Then there are people (my self included) that have found the door wiring harness connectors to be the problem. The wiring harness exits the door between the two door hinges through an accordion tube. Then they connect the the main wiring harness behind the kick panel in the foot well. I manipulated the plugs and got mine to work normally.
Start with the easy free stuff first and let us know how you make out.
