1999 Boxster 986 both power windows and convertible top not working
Hi All,
Last week the positive cable on my car broke off and my car was left with no power. In order for me to pop the hood to access the battery, I initially tried putting 12 volts directly to the C3 and D1 fuses. I think I burned something out. My interior lights work, the window drops when opening and closing the door, but both power windows and my convertable top don't wor.
Any ideas what it can be? My fuses are good, I swapped them out and am getting 12 volts, but it doesn't seem like my switches are getting any power. Could it be a relay? Do the power windows feed through the convertible top double relay? Any help would be appreciated.
Thanks

Whenever a relay is involved the techs have a bypass relay to use to eliminate the relay as the problem. It might be worth the expense of just buying a new relay.
In the meantime, what you can try is do a battery disconnect and long enough to ensure the car has lost all residual electrical power then reconnect the battery.
If required for your car, be sure you have the radio code.
Be sure the ignition is off and the key is removed from the ignition switch.
Follow proper procedures when disconnecting the battery and then connecting the battery.
If the switches still do not respond when they should (the key has to be on IIRC) and power is good then there is a fuse, relay, or other electrical problem. This could include an ignition switch problem though the behavior you describe is not any I have read being associated with a bad ignition switch in the past.

Thanks Macster, I already tried the reset procedure by disconnecting from the battery and putting the cables together, I left it for about 45 minutes.
I was thinking the same thing with the relays, to bypass it by putting a wire from one side to the other, my problem is that I don't know which terminals I need to connect the 2 sides of the wire to in order to bypass. Any thoughts?

My advice would be to pick up a Bentley Porsche Boxster Service Manual. In the back it has the wiring diagrams for -- in my early copy -- a 1998 Boxster. From the diagram you might be able to deduce how to bypass the relay.
In the meantime you might visit Pelican Parts. It has some write ups on various Boxster services/repairs and it may have a write up that has some info on this subject that is useful to you.

thanks workaholic, I did check, it's ok, I even checked the board as per Pedro on his forum, looks fine to me.
