I have a 92 SSEI when i got it about 2 months ago the door locks all worked fine.About 2 weeks ago the passenger side stopped working and 3 to 4 days later the driver.The front switchs {driver and passenger} will still lock and unlock the rear doors. I have changed the door lock relay that is clipped to bottom of passenger side fuse block, but still no change. Any ideas?

could be the bottons?

I thought about that. I will replace both just to be safe, they can't cost that much!

i think there kinda $$

I guess there still a dealer item only?

Try checking the ground bus.

The switches would be a dealer or junkyard item. Do you have a voltmeter?

I agree with Ted. Check the grounds he linked first. If they're good, or cleaning/greasing doesn't help the problem, investigate the driver'* switch first. It'* the master switch that controls all doors. Clean and grease those connections, then we'll start digging deeper.

Thanks, I will give a try and let you know what happens.
