I have a 03 acura tl and having window issues from the driverside switches. All other windows work with their individual switches but not on the main driverside(d/s) switches. I have replaced the d/s main switches and it did not fix the issue. Is this a window relay issue from the d/s and how can i go about fixing this. I hate having to reach over to each window just to roll them up/down. Much help is appreciated!

ive been studying the wiring diagram which im usually pretty good at but something about power windows just make me a little uneasy. Anyway, it wont let me post a link to the wiring diagram
That system does not use a relay if memory serves and since the other windows work with their own switches I think you can rule out the motors. I think the most likely suspect is the master switch based on your description.
Check the main switch inside the power window master switch. That main switch controls all the other switches. If you look at the second page of the wiring diagram you can see it.

According to the diagram there is a relay. However, if that relay was no good, none of the power windows would work. I do believe it is the master switch. Or the main switch within the master switch. If those check out fine, then the only other possibility is the door multiplex control unit.

+1 with looking at a wiring diagram. I would be checking my feeds and grounds.
Keep us posted!
ok I have looked on youtube but have not found anything specific to my issue. I have checked the wiring diagram on the bbbind site and they have one for the 04 acura TL. I’m going to assume its similiar but I still cant figure out where exactly to look. Again the switches on the d/s do not work except the d/s switch. All other windows and their individual switches work.
The pw repair video in the electronics section helps a little bit but the chevy cavaliar and the acura tl have window switches in different spots. My acura has the window switches in th d/s door whereas the video shows switches in the middle console almost like BMW’s.
just pop out the switch and use a testlight to see if you have voltage at the wires while you push down on the button (key on of course)

ok I’ll try that when I get off work today.
2 possible things that could happen:
1. Let’s say that I am getting voltage to the 3 non working switches on the d/s controls what would be my next thing to test/check?
2. What if there is no voltage to the 3 non working switches on the d/s controls what would be by my next thing to test/check?
first off i think i forgot to ask, do ANY of the drivers side switches work? Can you roll down any of the windows using the drivers side switches, including the drivers side window?
If you dont have voltage I would check your relay. Place your finger lightly on the relay and have someone activate the switch. You should be able to feel it click
yes fuses were checked. I tested all the switches and they all checked out fine. I decided to check the door jam and pull back the rubber protector only to find out that the red and green wires were split. I removed my speaker to get some leverage and slack rewired them together w/ electric tape. According to the diagram looks like the red and green had something to do with the power. Probably another reason why that speaker wasn’t working either. Glad it was just that instead of a possible multiplex control unit which would have took a good dime out of my pockets.
I appreciate all of your input in getting this issue fix.

so all the windows work now? the wires taped back together should
really be soldered and heat shrinked to be a proper repair. also a
speaker wire should have nothing to do with window power.Hey, if it works, then problem solved. However, I didn’t see anything on that diagram that suggested speaker wires were on that circuit. Maybe it was spliced into the circuit by the previous owner if it’s a used car. Also, you should solder and heat shrink it. Tape is no good.

I should have mentioned this from the beginning but my lock-i should mention that my keyless stopped beeping when i hit lock, window switches (minus d/s switch) and speaker on d/s were all not working and all went out at the same time. I thought these were going to all separate issues that I was going to ask on this forum.
Speaker may have nothing to do with window power so one of the those wires was for the speaker or locks or both?
I know I should have soldered but this was a temp fix and may do it another time since I know exactly what my issue is. There’s just not much room in the door jamb and even splicing the wires was little difficult.
