'90 200q - A few nagging problems
1. My '90 200q windshield wipers are giving me
fits. They want to turn off about 1/2 to 1/3 of the way up the
windshield. Also, if I have them on intermittent, they stop part way up
between pulses. Sometimes they correct themself after while if I leave
them on. I have found out that I can get them to stop down on the bottom
if I use the one-wipe function (pull down on wiper switch) and only pull it down
for a split second. But then the next time I use them they are screwed up
again. What governs the stopping point on these things? The real
puzzler is the fact they self-correct after while, although this has only
happened twice, now they seem to be messed up all the time. Anybody else
had this problem?
2. Every once in a while my windows will all fog
up. I know that this is caused by the re-circulation door under the dash
on the passengers side sticking open. The question is, why does it stick
open? Bad spring? Need lube? Bad vacuum line? I would like to
know a little about how this thing operates before I go tearing into it and
really screw it up.
3. My rear window defroster doesn't work. When
I push the button there is a slight delay before the light comes on, but nothing
happens on the back window. Is there a connection point that commonly
fails on these, or could this be switch failure? Today I am going to look
under the rear shelf and try to find the wires for it. Another problem
that seems like it might go hand in hand with this, is my AM/FM radio reception
is very poor. Car has the Audi/Bose system and I have read that one of the
antennas is built into the rear window. Does it use the rear window
defroster wiring for the antenna? I'm hoping that fixing one problem will
cure the other. If not, how do I get to the back of this stupid radio to
make sure the antenna is plugged in good into the back of the head
unit?
4. The steering on this car seems quite heavy to
me. Is this an indication that the pump is going out? I remember
reading someplace here that there is an adjustment on these to set how heavy the
steering operates. How do you adjust it and is it something I can do
myself or is it better left to a mechanic?
Thanks in advance,
Tony Fordham
