Toyota Repair: 1990 Camry master window switch, window switches, door switches


Question
QUESTION: Ted, the indiv. window switches work on each door, but the master drivers door switches do not.  The door lock and window lock on the mstr. sw. work.  I bought a used master sw. and it does not work either.

ANSWER: Do none of the windows work with the master switch or only one?

QUESTION: None of the windows work by using the master switch panel.  Only the window and door locks on the master panel.

The window switches work on the rear and passenger doors.

ANSWER: It's possible that there is a wiring problem in the wire harness from the window switch to the inside the left kick panel where it connects to the junction block, sometimes the wires can get stretched and break inside the insulation just from oprning and closing the door over time, not very common but I have seen this be the case, another thing to check is the master window switch ground, check the white/black wire at the switch connector to body ground for continuity.

QUESTION: I rang out the 2 white wires, both are grounds.  There appear to be two green wires that are hot.  I took apart the master switch case and there appears to be blk. carbon on a couple of the contacts, but not all.  What color wires could I jump with a hot to see if it the replacement master switch control?  Do you know how many hots, or color of them that are supposed to supply the master controls?  Do you know what color wires are the travelors that go to each separate doors' window switches?

Answer
The blue wires going to each of the switches including the master switch should battery voltage with the key on,The grren and red wires go to the left front window motor, the grn/wht and red/blue go to the right front switch, the green/yellow go to the left rear switch, the gren/blk and bed/blk go the the right rear switch, these wires should not have voltage unless the switches are either up or down, they are for up/down only.
