I did a search, (just in case some of you are wondering) and didn't come up w/ any answers to THIS probelm.
I have a 1997 ES300 w/ ~140k miles. She's been very reliable so far, but just recently the power door locks quit working intermittenly. At first I thought it was the remote, so I replaced the battery. Same issues still happened. I remember SK saying somethign about the terminals getting all cludged up w/ debri over time from arcing, so I decided to take the drivers side switch out to inspect it. I found that it was fairly dirty, so I cleaned it w/ WD-40, and di-electric grease where appropriate. I reassembled hastily because I had to get to class. After working on the switch on the drivers door, it now decides to unlock itself randomly. I have since not driven the car for fear it will just leave itself unlocked when it's on the street when I'm in class.
My question is this: For anyone who is familiar with the electronics of this car, would the symptoms that I'm having now be solved if I order a new switch from lexus for the drivers door? Or does the problem stem deeper than this? The switch was $200 last time I checked so I don't want to start the expensive guessing game w/out first checking the LOC experts!
Any advice may help. Thanks in advance.
Cheers!
