Well Jim, the reason I question the mechanic is the same reason I questioned
the same shop after they did front brake work on my '98 Malibu, which are
well known for front brake problems. After only 2 months, one of the
calipers started seizing up and I could not understand how this had not been
detected when the original work was done. I was also really puzzled as to
why they couldn't tell me what condition the opposite caliper was in, seeing
as how I didn't want it sticking as well. Needless to say, I haven't taken
my car back to that shop. At one time, this used to be a reputable shop.
But now that most of his mechanics are young "kids" that are half my age, I
just don't trust them anymore.
With that aside, I'm not sure what you mean when you say interval operation.
If you mean, do they wipe, stop for a set time and then wipe again, then
yes, but only on the Hi or Low speeds. The wipers will not function at all
on any of the intermittent settings, I tried this yesterday. I waited up to
a minute on the fastest setting before it clicks to Low and there was no
wiper movement at all. I also tried all of the intermittent settings in
between (probably about 10 in total), nothing. I agree, any inspection I
did as an Apprentice (more than 11 years ago), the wipers and the sprayer
had to be working as part of the MVI.
So my question now, is the GEM part of the wiper motor assembly, as Mike
suggested, or is this a small module located somewhere else? Mom has
already priced up a new wiper motor @ $110 from the dealer, and she was
going to call around for prices for the MF switch on the steering column,
which I suspected. But, as I admitted earlier, my wrenching experience with
cars newer than 2000 is limited, so I would rather ask someone more
knowledgable than I.
Suggestions are still welcome, and thanks for the replies.
