93 camry wagon rear lighting problems

[swed]

Hello all, I am new here and my problems drove me to know you,

Main sympthom is

1, All rear lights are off while their switch has turned on(evening/night driving mode), except license plate is on;
2, front lights and all braking lights work well(properly)
3, no blow(bad) fuses & bulbs found from all fuse boxes as shown in owner's manual(three boxes in engine compartment, one locates underneath Instrument Panel and another one locates Passenger's side kick Panel);
4, fuses those concerns to lighting had been exchanged each other for testing purpose and the problem still there
5, voltages @ bulbs-mounted bases could not be detected by multimeter when night driving switch mode is on;
6, warning indicator in Instrument panel is always on and it show the problem existing properly.

possible causes and problems solved

7, At very beginning rear left braking didn't work and found its bulb with fault short(connected each other within two worn tips(nips) of the bulb(double filement), cut it and the bulb work fine

confused questions

8, none rear side lights(bulb, model 194 as instructed in manual) were found( I checked all bulbs@rear lighting bases);

9, there is a text instruction for rear side marker lights in p.214 of the owner's manual but none illustrating figure in further pages at all. combining with #8 above, what bulbs should be for rear side marker lights?

10, I doubt #1 above was cause by #7 but none of fuses found to be burned; maybe a related relay burned?

11, With "Haynes repair Manual" 92 thru 96, all models, found no significant info so far. How and where I can get effective info for these problems?

all u, any suggestion and experiences are welcome!!

Thank you very much!!!

Most rear lighting problems in Camrys stem from the wiring loom located in the trunk by the trunk hinge on the driver's side. All the opening and closing of the trunk flexes the wiring in there causing a break or multiple breaks of the wires. Open up that loom and look for broken wires or frayed insulation. If you don't see any obvious broken wires, you will need a DVM (digital volt/ohmeter) or at least a 12 volt test light to track the problem down.

Good luck.

Mike, Thank you very much for your messege!

I have the difficulty to understand the location of "loom". Today(Nov.13) I got a 94 camry manual( http://camry.turboninjas.com/camry94wiring.pdf ) and I will search the loom. Thanks again!!!

swed,

It's right by the left (driver's side) trunk hinge, inside the trunk. You can't miss it.

The word "loom" meeans a "bundle of wires," swed.

Have you checked the taillight relay? It's on the opposite side of the fuse block under the dash on the driver's side.
FWIW
YMMV
