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!

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
Only d/s switch on d/s works, all other 3 on d/s do not work.
Again with scenarios:
1. What if I do feel or hear clicks in the relay, what next?
2. What if no clicks should I automtically assume relay or also check something else?To confirm:
Is #15 on this site the relay I should be touching when testing for clicks?http://acuraautomotiveparts.org/acura/j … CABIN+ROOM)&ListAll=All&vinsrch=no&systemcomp=List%20All&vinnoT=&trim=&trans=&view=normal
I believe #15 is the correct one. Im not familiar with acura products but It would be the power window relay in the fuse box. If it doesnt click I would check that you do have power where the relay plugs into the fuse box. If you do, replace the relay.
Also, if the horn or something like that has the exact same relay ( and you know it works) you can swap it out and check the windows. Its also possible that maybe you just got a bad (new) switch
the fact that one of the switches on the d/s master switches work leads me to believe that the relay is probably ok and maybe you have some pinched wires or corrosion. Maybe inspect the switch again and see if anything is out of the ordinary
Also, if you have some jumper wires you could pull the relay out, energize it, and see if you have continuity on the switch side of it
according to that picture there are fuses. have those been checked?
also if you suspect a relay you could try swapping another relay next to
it to try itive 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.
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.
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.

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.
