Toyota Camry Electrical Problems
Q. I have a 1991 Toyota Camry. It is a 4 cylinder with an automatic transmission. It has between 130,000 and 140,000 miles on it with fuel injection. It does not have ABS brakes. It has power windows, door locks, and it has cruise control, the manufacturer radio in it, rear defrost, A/C, an overdrive button on the Gear shifter, and a power button between the drivers and passengers seat.
It also has a seat belt release for the automatic seat belts. There are no air bags in this car. I have power steering.
This is my problem; when I step on the brake the light on my radio goes out. The light on my heater panel is off most of the time but some times it comes on. The panel on my dash board that displays what gear you are in the 'R' stays on and the Overdrive and the power light no longer works. My reverse lights do not work. My "lights" light is lit on my dashboard. I changed the bulb and checked my fuses and they were all fine. I seem to be having some electrical problems with my car and am not sure where to start when it comes to fixing it.
Thank you for your help.
Ja-NitaA. It's no wonder you're confused as to where to start, with all of these strange problems going on, I'd be hard pressed to find a starting place.
If all of these problems occurred at once, then I would think it's a problem with the harness itself. Maybe somewhere it rubbed through and it's causing the lights to go on and off at will.
I guess I would start with the H1 connector. It's a yellow 20 pin connector that's inside the left hand kick panel. I would check it for looseness and make sure it is clean and tight. I would also get under the dash and look at the main harness where it goes above the brake pedal linkage. I would think that's a likely place for the harness to wear through.
I wish I had some sage words of wisdom that would take you directly to the problem, but I have none. If a check of the connectors and harness does not reveal the problem, you will need to test each system in turn. Hopefully when you find the problem with one system, all the others will be fixed as well.
