HELP PLEASE: 98' Sienna when turning left causes map light, door ajar, doors unlock

Hello all.

Just wondering if anyone has had these issues and how they got them resolved. Recently on our 98' Toyota Sienna van, when we make a left turn the following occurs: map lights come on at the same time the door ajar comes on in driving panel screen and if you had the doors locked, they will become unlocked.

This only occurs when you turn LEFT, I can never get this to occur when turning RIGHT.

This happens I would say 80-90% of the time when turning LEFT..


Any suggestions out there as Toyota Service said I would need to spring $450.00 just to have this analyzed before even fixing the issue.. I really did not want to shell this out let alone let someone go rooting into the electrical system..


Thanks much.

We had this problem, too. 1998 Sienna.
I thought my wife was kidding, but I saw it with my own eyes!
I even put the car in the driveway, started the engine with the door OPEN (and my finger on the door switch), and fiddled with the switch until I replicated both the "unlock" and interior lights problem.
Solution: I added a ~1/8" thick x 1" x 3" piece of adhesive-backed rubber over the part of the door that triggers the switch. No. More. Problem. Our problem was with RIGHT hand turns, so I found some VERY aggressive right hand turns to test it out...all is good!

BTW: Right hand turns means you have to fix the DRIVER's door. Left Hand Turns (I would imagine) you might want to focus on the front passenger (right) door. I looked at the little flat-topped "hump" on both doors, and the left-hand (Driver) door was definitely "dimpled." The right hand door was not.
