If it's any consolation the problems with your car are minor in comparison with the problems I had on my mexican beetle.
Nearly 200,000 miles and two gearbox rebuilds (it first went wrong at 120,000). First time round 4th gear's layshaft keyway wore its self out and very nearly lost 4th gear, second time round (it was my fault for trying to get my mexican beetle to the hard shoulder with a snapped clutch cable) 3rd gear was jumping out. £740 first time around, £500-odd second time around.
I have also had a partial respray done to it as well, but I'll need to take it to a decent bodyshop to get the rust off it (and possibly minor welding since I don't have time to do it) and all that for a car that's under 9 years old.
You could try changing the wiper motor (they're fairly cheap) if the wiper switch is ok. The wiper switch can be easily checked with a multimeter (on continuity test) with the plug removed from the switch.
What carb do you have on your car (and what dizzy does it have)? Ideally the carb and dizzy (preferable single vacuum advance dizzy) should be suited to the engine its self (eg. Solex 34 Pict-3 or 4 for a 1600 twin port engine). So called brand new carburetors are usually a waste of money (as I found out with a Brosol H30/31).
Good luck with getting your car fixed.
yep, your problems are worse!

ive tried different switches and its the same, so all i can think of is the motor. am crap with engines, so know nothing about what sort of carb it has or dissy! it all goes striaght over my head!
