Intermittent Light problem

Hi,
I have a strange intermittent problem with my parking light.
I can start my car in the morning and go to work, it takes me
about 15 minutes. At all the time there is parking light and tail
light. Then if I drive again after 1 hour, 30 minuets or five minutes,
the parking light does not come on! I have taken all light units apart
and can not find any visual problem. I have sprayed all connectors
with WD-40, but no good. When the parking light is working there
is no way to interupt it by fiddling with the connectors or kicking,
shaking or rolling! The same when it's not working. No matter what
I do it will not work! Give me a clue where to find this problem!

Pepe

Re: Intermittent Light problem

A start would be to know a bit more about the problem. Are all parking
lights, front, rear, left, and right, involved? If you have side marker
lights, are they involved? Do you get a bulb failure warning? You need a
wiring diagram; the ones in the Haynes manual are fairly good. Be aware that
the lights are controlled by the four lamp modules, one at each corner of
the car. Each module has a 6 or 7 relays, one for each lamp. Each front
module is fed from 3 fuses and each rear one from 2 fuses. One fuse to each
module feeds the low power lamps. If all 4 lamps are going out the problem
has to be in the control from the switch which my diagram shows as a common
red wire to all 4 modules. It also shows this lead to be controlled by a
"AUX SIDE LIGHTS RELAY" through a BLU/GRN wire. Without a wiring diagram,
the best thing to look for would be bad connections at the fuses, control
modules, relay, or switches. My car is a 1990 model and yours may be
different. Perhaps someone else can correct me if I am in error. Hope this
helps somewhat.

Re: Intermittent Light problem

Thank you Don Young for answering!

Yes all four parking light goes out at the same time.
I have no side markers with lamps inside, only rear
side of the car have marker and only reflectors inside.

There is no bulb failure warning. There are light in the
instrument cluster at first and second step of the light switch.

Do you know if there are some relay that turn on the parking
light? Do you know what module is giving the parking light?
I have found one unit under the steering wheel where all calbles
from the light switch ends up. I have sparyed all these connectors
but it will not help. There is always parking light when I start the
car in the morning or in the evening after work. But when I am
home after about half an hour there is no more parking light, and
worse, no tail light. The front parking light is not so big problem...

I have the Haynes Repair book and several CD with wire diagrams
but I can't find out how the parking lights are connected. Or what
component that is wrong. Could it be a transistor that gets overheated
after a while and then when the car has been parked for some time it
cools down and the working again for 10 - 20 minutes?

Any help is welcome!

Thank You

Pepe

Re: Intermittent Light problem

On page 12-22 of my Haynes manual it shows the parking or side lights turned
on by grounding a BLU/BLK wire from the FACIA SWITCH PACK. This energizes
the AUX SIDE LIGHTS RELAY if +12V is present at the BRN/YEL wire from fuse
B2 in the right fuse panel. When this relay is energized the ground at the
BLK/PNK lead connects to the BLU/GRN wire. This wire is connected to the RED
wire which goes to the four bulb modules to turn on the lamps. This is the
only part of the circuitry which is common to all four corners of the car
and seems to be where your problem lies. I have the JHM 1126 CD which has
more complete wiring and location diagrams but is harder to search. I am in
the process of looking for more information there and will let you know if I
find anything else. Page 12-5 of the Haynes manual shows 2 side light
relays near the right of the console, but I do not know exactly where they
are located.

I do not think your problem is a transistor as I have not noticed any common
to all four lamps.

AUX SIDE LIGHTS RELAY

Thank you very much!
I think I found the problem thank's to you!
It seams to be a bad coonection to the relay.
Thank's to you I could find the relay and when
I started to finger the unit the lights came on!

This one was never touched before and there
vas come green corrosion on the connectors.
I have cleaned the connector and also the
relay module and now it seams to work again.
Thank you very much!
