7x15 ET38 on type 89 and NO #%*&-ing headlights

>Anyone got any experience mounting wheels of said dimensions on >either a
FWD or a q type 89? It isn't lowered, tyres are 205/55.

I have them with ET37 (the S4 style 5 spokes) on a 1988 90 Q.  Tires are
205/50X15, not lowered - no rubbing by a long shot, look nice, what else?

My questions:
1. How does the lower plastic piece under the combination switch on the
steering column come off?  Patient - 1988 90 Q

2. Is this the typical combinaiton switch failure?
- flickering headlights for a couple of days, both high and low (dipped)
beam
- last night - turning low beam on was fine, then high beam was fine,
switching back to low beam - darkness.
- The park lights are fine, the high beam flasher (Lichthuppe) is fine, all
fuses are fine, what else, except the switch, wiggling doesn'e help.

3. Is there any temporary fix until I get to it, apart of driving during
daytime only.

TIA
