2002 civic 1.7 power windows
|
|
|
Each switch has 5 terminals , rear drivers has one with the 12 V's , 2 for the motor and what should be 2 grounds one has nothing and the other has 12 V's , the front pass. has the 12 V , the 2 motor pins , and 9 V's on the last 2 , When I start it up those 2 get 11 V along with the 14.5 the power one should have . Is there a common area/junction that these problems may occur ? I hot wired the rear drivers just to get it up , didn't try with motor the front pass. because I think there's obviously a problem . They may have quit at the same time or separate , not sure . No drain on the batt. but the radio is after market and there were a few derelict wires from the dash and firewall l that I cut/tucked away so no telling what was done in the past . The windows worked for the last couple of years so if there's a starting place I would be grateful , thanks .

Windows are complicated circuits because 1) they are operating the same window from 2 locations, 2) the circuits reverse polarity through the switch to reverse direction so you really need to understand these circuits to diagnose the electrical circuit.

Doc D: Just asking where and why voltages are all over the place? A drop to 9 at one test -- WHERE? Were doors open and key clearly to enable windows at all taking time with interior lights on is going to get you low voltage FOR TESTING if long enough. If it was running fine forget this note and move on about some of it.
Seemed you found power at switches just I question why they varied so much from "battery voltage" at the time? You jumped one to get it to go up? Just what did you do for that so it worked? Only point is if losing power or grounds thru switches one master or at the doors finding right where is going to be a chase.
Also - since the rear one didn't work does this have a choice to only allow driver to run windows or if on console just the fronts? That if just rears is then suspect. This could be quite a corn-maze to find out where and why it drops off like that if tested under same situation or this is off on a goose chase it's something else causing this,

It was the lock out button on the master , I'm such a twit , I assumed the master would still work them when that was on . The key was KOEO and the door was open when testing . To get the drivers rear up I disconnected the motor clip , got power from the other disconnect and grounded it out on the hinge bolt . The pass. front works I just have to pull the panel on the drivers rear and hook it back up . I left it off so that it didn't possibly go down and get stuck there . Thanks for the wiring diagram though .
