ELECTRIC WINDOWS ACTING STRANGE

[Wellsyboy]

Hi just bought a 2007 8P 170 S Line got a few issues that were known about one that wasn’t. The electric windows go up & down ok then won’t work usually when they are down!!!!!! Strangely if I completely turn off the car & re start it they work so something must be resetting. Guess like most things it will be a known problem so apologies if this is an old story. How do you fix this??? new relay???

I'd recommend a diagnostic check to see if any fault codes flag up. 

It could be the driver's door electric switch control. 

Or it could be a failing comfort control module. Have your carpets get wet?
