Hi everyone,

I´m from México and I have a Vectra "D" Confort, but unfortunatly it have a problem lately. Every 3 minuts after I start the engine, every electric device in the car goes off. I've got no temp gauge, no rev counter, no speedo, no fuel gauge, no oddometer readings etc... Windows still function but after a while they stop working. The engine still working and it comes again to normal just after I Turn off the engine and strat it again. Other thing that aparently comes with the malfunction is that the transmission became slow, the speed changes get out of time badly.
The only code I get is P1704.
I dont have any Manuals, or díagrams to check anithing. so,If any of you have any opinion or sudgestion it will be great help.

Thanks and greetings from Mexico.
