Intermitent electrical failure on golf

Did you check voltage and ground, anywhere?
F2 16--30 amp fuse at the top, did you check that fuse for voltage? Use a test light or something, key on. Is it hot? If so, pull the run park relay, use jumper wire between cavities 3 and 5, switch side of relay, right side in diagram. The wiper should work on lo speed, depending on the problem. You should have done voltage and ground testing before replacing anything. You may be way ahead of me as far as testing? The relay has two sides, the switch side and control side, the control side needs voltage and ground to energize. The gem module ground relays based on input from wiper switch. good luck

Do you know what a wiring diagram is ? How to use a DVOM - digital volt ohm meter to test automotive electrical circuit's ? Do you know anything about automotive electrical ? Free wiring diagrams here http://www.bbbind.com/free-tsb Enter vehicle info. Year , make , model and engine size . Under system click on body & accessories , then under subsystem click on wiper/washer . Click the search button then the blue link . Looking at the diagram I see the wipers are controlled by an electronic module (GEM) . The switch is an input to the GEM which controls relays to turn on the wipers . Do you know what DTC'S - diagnostic trouble codes are ?

What seam's to be the problem ? Would hate for you to replace the switch an have it not fix the problem .
The wiper's not working ? There is a whole list of thing's that could be the problem . Same for the dash light's ?

To determine the cause of a blower fan failure, isolate the motor, and perform some basic electrical tests.Check fuses first. Fuse failure often causes component failure. Check for power at the motor itself. Test the connection to the blower motor. Test the switch.-------------------------------------------------------------------

Most probably it is a relay problem. First check from car manual which relay is commanding to your wipers, blower etc... Then you or your service have to replace it.

it could be either the forward control modual or the fuse box under the hood.
