3-4 minute delay for wiper, indicator start

Hi,
Passat TDI, 2000, 1.8 deisel, comfortline, when I start the car there is a 3 to 4 minute delay before the Indicator, Wipers and air conditionar will work, everything else seems to work o.k. Also when I switch off the car and remove keys the rear window demister and wipers remain on.

Is there some delay circuit to stop everything starting at once??

Any help will be appreciated....

I don't know of it as a common problem for the '00, but it sounds like the electrical portion of the "ignition" switch is bad. Try jiggling & slightly turning the key in the switch to see if things start working properly.
