i have a 91h gsi 3000 andwas wondering if any one could help? the prob is the dash keeps going out until the car is warmed up inside, or the outside temp is above about 15c it flashes on and off and is really starting to p me off ! Ive put in a 2nd hand auto one but that does exactly the same thing!.

could it be anything to do with a loose main earth ? or just one from the dash ? any help would be much appreciated. and how easy is it to take out the rear window motor r/n/s as this has gone too?
My Senator one used to do this until it got warmed up. Thumping the dash usually helped until I replaced it with a repaired one.
If you open it up, (a bitch of a job in itself 'cos it's fitted with anti-tamper screws!!), you'll find dry joint(s) which will need the attention of a soldering iron and fresh solder.
