Hello,

I have a 02 Tl Type S. All of my windows except my front left window work. At the master driver switch I could open and close every window except the driver window. I thought maybe the switch was bad so I replaced it. No luck there still didn't work. So I thought maybe it's the regulator and motor. Nope! Replaced that and it still didn't work. I know this is all kind of backwards but I then checked the fuse and it had indeed blown. So I went ahead and replaced it. Only thing is my battery is old and I'm trying to sell the car so I didn't want to shell out too much for a battery so I use a jump pack when I need to move it. Well after I put in the new fuse and tried to jump it using the pack it said "battery protected, unplug and try again". When I take the fuse out it let's me jump the car no problem. Does anyone have any thoughts? I just pulled the relay out and I'm going to put in a new one, but it wouldn't make much sense for it to be bad because all of the other windows work.

 

Sounds like your fuse is closing a circuit in an undesirable way. Have you tried removing the door switch (the plug that leads into it) instead of the fuse? perhaps there's a problem there and that's causing the problem. Shame that you replaced the motor and regulator without checking those other things...

 

Thanks for the response tiger. As far as the door switch, what do you mean? Do you mean the switch that controls the driver side window? Because I replaced that. Thanks!

 

Sounds good. Do you have the service manual? after taking a look I failed to mention the power window relays, have you tested them?

 

Here is the link to the manual.
