Not sure what the problem is with my rear driver side window? I have an 03 honda accord and when i hit the window button inside the accord it won't put that 1 window down... But when I hit the unlock button 3 times on my key less entry it puts the window down... What's do you think the problem is?

well, i'm going to say the driver side master window switch is faulty, but i don't have time to look at the etm atm, i'll check it out later.

thanks for your reply... Please let me know if you think it could also be something else... Could my stereo have an effect on the switch...

I have:

JL AUDIO 10" W7
JL AUDIO 500/1 AMP
JL AUDIO CLEANSWEEP

Just taking a guess that maybe this has caused the problem?

audio will have no effect on this situation fyi.

does the window open from either switch?(driver door master switch or drv rear door)

so yeah, it looks like the multiplex uses direct control of the window circuit when using the key fob to lower the windows. the switch uses a convential switch circuit with can fail from usage. but which switch is bad? the drivers front master switch or the drivers rear switch? they run in series with each other.

testing the switch can get complicated, since there are two different relays with a silly little schematic, i can walk you through it if you have a dmm. honda says swap with a known good switch as a test. figures. here is the schematic.



as you can see you have down+ and up+(multiplex controlled from key fob and drv. master switch usage) and the hot w/ key on(used if the switch in the drv door is used). not very fun to diag is it? swapping a known good part makes it very quick and simple.
