Question about 1999 Toyota Camry
How to test for particular relay switch, dashboard indicators fuel, odometer,auto lights not working. all windows inoperable. will start however if run the battery will drain until it stops the operation of vehicle. what and how to check the system. thanx
Get a wire with a 12v light or a TEST PROBE. Put the Probe between the NEGATIVE WIRE and the NEGATIVE TERMINAL (you can also do this with a Multi-Meter (but make sure you have it set on the HIGH SETTING with the Plugs so you do not burn up your Meter.
Doors open will put a drain on your battery so shut the door and wait for the lights to go off *(up to 5 minutes).
Pull one Fuse at a time and see what happens on the Drain. When it goes down low, you have it narrowed down to a system
Then troubleshoot internally of that system.
Alternators are known to do exactly this.... Food for Thought

Open the rear hatch. Pull off the inner trim panel. Look to see if there is a little box with a bunch of wires connected to it. It may be at the lower edge, driver side. Turn the key on. Test for 12 volts at the solid BLUE wire (there is only 1 solid blue wire) that is connected to the box. Is there power? If not, check the 30 amp POWER fuse. If there IS power, this box may be bad. This is the power window relay for the rear hatch. The wiper/washer and the rear window motor power all come out of this box.
Check for power & get back to me before you buy a relay box, there are a few other tests I could share with you before we pronounce the relay box bad...

as long as your volt meter is capable of measuring OHMS you can test wires, find the main power wire to the fuel pump and measure for voltage when you turn the key on(3-4 sec) if power is present at the fuel pump, and the pump don't run, then replace it

Even though the relay is activated,I assumed you checked the out put?Also,You checked the voltage at the light sockets?With a meter,or test light ,check the fuse for the cluster lps,adjust them to dim,and to bright,the meter should act accordingly on the fuse.If it does not,replace the dimmer control,or head light switch,witch ever controls them.This may allow continuity to the tail lights as well.If the fuse is dead for the cluster lights,replacing the dimmer control,or head light switch will solve the problem,or,from another fuse ,supply voltage to the cluster lp fuse,one that is only hot with the key on,cause if you do this the dash lights will come on,every time you run the vehicle,day,or night.

This may be the location: There
is a power main relay, it's located on the rear of the junction block in the left side of the dash behind the cover, on the front are the fuses and on the rear is the relay, it's the one closest to the center of the car, there are two other relays, these are identical so you could swap one of them and see if that fixes the problem.
If that doesn't do it, one cheap way to find this info is a Chilton manual at the library.
