Car and Truck Sun Roof Information Questions
Question: 1999 Toyota Celica, mileage: 126,000. I am having a problem with
the sunroof. It will open with the up switch but not with the slide. All I hear
when you depress the button is a clicking sound that the relay is making. You have
to manually screw the roof closed. I manually opened the roof and it would partially
close, but not run the other direction. Now the motor is 12 volt, so I assume that
open or closing, all it is doing is reversing the polarity of the motor to get it
to run in the opposite direction. It will open in the roof up button, but only close
in the slide mode. My guess is that it is in the relay, but that unit is $300.00
from Toyota. I would like to find out for sure before putting out money for no just
cause. Any suggestions?
Answer: We would suggest isolating the wires
that go to the sunroof motor and applying 12 volts and ground to verify that the
motor is working properly. If it works in one direction, switch the wires to verify
that it works in the other direction, fully closing and opening the sunroof. If
the motor checks out okay, then the relay is your problem.
Question: 1999 Honda Accord, mileage: 100,000.
The moon roof on my accord leaks but otherwise it seems to function fine.
The dealership said the entire assembly must be replaced. Seems expensive
and unnecessary. Is there a seal kit available? Is it difficult to access?
Anywhere to get instructions for accessing this area?
Answer: The best thing to do is check with a Honda dealer
and see if they can order one. Simply remove the head liner to replace sunroof motor
with new reassemble to recheck operation.
Question: 1998 BMW 325i, mileage: 115,000. I rolled down the windows
on my car and let the sunroof back. For some reason the sunroof or any windows
in the car will not move. I have tried all the window locks and they won't
work and looked at the fuses and none are blown. If you have any info, Please
help me.
Answer: Your car is equipped with a body control module.
It controls the windows, door locks, sunroof etc. Scanning the BCM will tell
you the fault codes to pinpoint the malfunctioning component. Replace as need to
repair problem.
Question: 2001 Mercedes C230 mileage: 71,000. I hope
you can help. My problem is that my sunroof is stuck open and I can't get it to
close. When I told my husband about the problem he just sat there and said those
five little words that I dread "honey take it to the dealer" oh please do you have
any idea what a hassle it is to take my car to the dealer. Well let me tell you
the last time I had to take it in to the dealer took me three hours to just drop
it off and get a rental car and I had an appointment. So please if you could e-mail
me back with some information for my husband that would be great. Thank you so much!
Answer: We can understand your husband’s response. But ere
are some things you can look at first. Check system fuses, also inspect the switch
contacts, (clean as needed) try rocking the switch back and forth rapidly, this
can break the motor free and let it work again.
