I tried to change the wiper blades and the manual says to turn the ignition
to ACC, turn on the wipers till they are in the upper position, then turn
off ignition to stop them there. I couldn't get them to stop, so was
wondering if it's just me not turning off the ignition at the precise moment
or if it is haywire. I'll get back to it later, but right now it's getting
close to 103degrees out side so will have to wait till this evening to fool
with it some more. Thanks.
If it is a newer Grand Prix, you may have the system that keeps power going
to some of the options after the key is turned off. Usually if you open the
driver's door, then turn the key off, the wipers should stop where they are.
I forgot to say that isn't required to do anything with the wipers or the
ignition to change the wipers. The only thing is it makes it easier to
replace the wipers if they are up. But, I would suggest turning the
ignition on, waiting till the wipers go up, then turning the ignition off
right away. Don't bother trying to turn the wiper switch off, as that will
just make the wipers go back to there lowered position. It's just a timing
On my '05 Impala it's damn near impossible to replace the wiper blades
with the wipers parked, as they're semi-hidden (work like hidden
wipers, but don't go down all the way below the rear edge of the
hood.) On the '08 it is much easier to accomplish, and as an added
bonus, GM finally got with the program and made the wiper arms go
"over center" when pulled up so that you can replace the blades more
easily and also leave them up overnight in freezing weather.
