They all work when open the driver's door. but nothing comes on when you open the passenger door. What should I be looking for?

 

there is a little button thing thats most likely stuck my driver door does this to me all the time i just pull it out and hit it with wd40 like once a month im sure its cheap to just replace but it dosent bother me that much

 

Yup, I 've already cleaned and lubed it, but no better......

 

id have to guess a bad wire somewhere then i dont think it would be a relay i dont see gm making a right and left side relays

 

I'd test the switch itself.

Curiosity led me to my shop manual:

CIRCUIT OPERATION

Voltage is applied at all times through the ACC FUSE to the components in the circuit. The COURTESY LIGHTS, CIGAR LIGHTER, and the DOME and READING LIGHTS each use separate switches. The LH and RH COURTESY LIGHTS and one of the DOME and READING LIGHTS can be operated by current flow through either the LIGHT SWITCH to G200 or through any DOOR JAMB SWITCH to ground.

TROUBLESHOOTING HINTS

If none of these components work, check fuse by operating HORN.

If several circuits don't work, check G200 (Behind I/P, left of steering column). G200 should be a thick black ground.

Interesting stuff James. This is a car I just purchased recently and last night was the first time I had a chance to look at it. The horn, interior lights, power mirrors and PDL were not operational. I replaced a blown 25 amp fuse and it all works now, except the interior lights when the passenger door is opened. I'll try to find the G200 ground tonight.

 

Charlie, replace the button switch in the door jam on the pass. side. They are cheap, like 5 bucks or less. Those switchs frequently go bad. It is probably stuck in the closed position. Even if the button moves in and out the internal contact in the switch get's stuck in the closed position from not being used very often. That's why you are having the problem on the pass. side. How often do you think that pass door has been used on a car that sat for 10 years.

It's super easy to change.

Also, do you have a test light or meter?

 

Thanks Brian. Maybe I should get a test light. How do you replace that switch?

 

Judging by the way both doors creaked, and how the locks were semi-frozen - not very!

 

Here's a pic, which may help you visualize. Note that the pass side switch has been discontinued.

Ok tools needed are
1 7/16 deepwell socket with Ratchet


Step 1
Pull ACC fuse.

Step 2
Place a 7/16 deep socket over the nut head on the outside of the switch in the door jam and just unscrew it from the body of the car. There is only one white wire connected to the switch and it is just held on with a standard automotive female connector. There is NO ground wire. The switch grounds directly to the body of the car.

To check power to the wire reinsert the ACC fuse. The white wire has a constant 12 volts going to it. If you have no power at the white wire then you have a wiring problem. If you do have power then it is just the switch.

Also the driver side switch listed in Modern Muscles site is the correct switch. Can be used on the driver or pass side. The only difference between the two switchs is the driver side switch has an extra male terminal on it. I have a drivers side switch in my pass side right now.

Here is some pics. Hope that helps,

 

That switch is available through GM PARTS DIRECT P/N 9662505 RH and also 9662504 LH. I would assume that it doesn't matter if it's a Pontiac or a Chevy,those nos.are for Pontiac.

 

I show that part numbers have been updated.

RH switch 9662505 has been updated to part # 20589218
SWITCH DR JAMB,(ONE CIRCUIT),(W/1 TERMINAL BLADE)
GM List price $7.86 Average wholesale $4.86

LH switch 9662504 has been updated to part # 25603977
SWITCH F/D JAMB
GM List price $14.24 Average wholesale $8.43

 

The switch just required some vigorous exercise and WD40. It seems to be working again. Thanks guys!

 

Clean the door jamb switch. It switches ground when you open the door completing the circuit. I end up cleaning mine usually when cold weather comes around. That's when they quit working. I check it by grabbing it and wiggling it lol and if the lights flicker then you know it's a bad connection.

 

My driver side switch plunger works but does not turn on the interior lights but the passenger side does. All my other electronics work too. I even plugged in a new door jam switch and it made no difference so I should be looking for a black ground wire to my fuse box?
