Wiring Diagram

Good day all !! Just wondering if anyone out there can put me in the
right area for an electrical wiring diagram for a '99 Corolla. Having a
problem with no dash light active with any door open, no alarm for when
headlights are left on, no seatbelt light, no trunk open light on dash.
I checked at the domelight for ground circuit on the door open
side.....have no ground here so I suspect the problem lies in a
controller for said circuits. Any help would be greatly appreciated !!

You can get online access to factory repair manuals and wiring diagrams in

Check the plunger switch on the door jamb to make sure it pops out when you
open the door. It may be stuck in the off position. The plunger switch is
under a rubber boot near the bottom of the door jamb. Carefully peel the
rubber boot back and lube the switch with WD-40. If the switch is good,
check the dome fuse.

The dome light works when in the "on" position...there is no ground
being completed when the dome light is in the "door" position (there is
a seperate ground circuit for each position). The dome light grounds
through the door switches when doors are opened......trouble is the
dome light does not come on with any of the door switches and it's
highly unlikely that all of the door switches have failed. I was just
looking at the schematic for my '94 Tercel and I really can't see there
being much difference between it and the '99 Corolla.......it's just a
dome light circuit !! BUT.....that's what makes me wonder if there may
be a time alarm control unit that controls warning lamps and buzzers in
the car.

Checking a door switch to see if a plunger is stuck in the down (open
circuit) position only takes about a minute, and it wouldn't surprise me if
all of the door switches were stuck. A 1 minute investment in time will
confirm or eliminate a stuck switch as the cause. I'd also check the gauge
and dome fuses.

The way the dome lights for the '94 Tercel and your '99 Corolla are wired
are probably the same or very similar, good enough for diagnosis.

All mine were bad in my '92 Corolla Wagon.

Thanks to Ray, all of them work now.

A little squirt of WD 40 under the rubber boot fixed mine...

Try it.
