93 Camry Lights dimming low/flickering

[nick bamberger]

I have a 1993 Toyota Camry LE, 2.2 L 4 cyl. 198,000 miles.
Lights have began to dim, and then return to normal, and repeat. They seem like they lose power for a few seconds, and then return to normal.
The lights are not completely going out, only dimming slightly. It is all lights, including dash lights and headlights.
It does this regardless of what instruments are operating ( radio, defroster, fan)

If weather permits, will test alternator tomorrow.
Wanted to see if anyone has had the same problem, and what took care of it.
Thanks in advance,
Nick

If you haven't changed the alternator brushes yet, it's time.
Kit is available from the dealer for around $20.
Also, check battery connections.

Connections are fine. Haven't been able to check alternator voltage.
Today I noticed that the engine RPM is dropping with the other losses of power.
Also there is a small click sound in the drivers side door when the lights dim, and RPM drops.
Drivers door power window switch has started acting up, maybe a wire is broken and touching metal? Would that cause the problem described?

I may go to salvage yard and try to find the p/w switch.

Unhooked the power window switch and that took care of it. Just need a replacement now.

Thanks for your suggestions.
