I have a 98 GS400 and the right rear door will not lock automatically. The lever moves about 1/4 of the way, then moves back to the unlocked position. This seems to only happen during the heat of the day, Dallas, 90++ degrees. In the mornings when the temp is in the 70's or 80's, the lock works as intended - no problems. The door unlocks with no difficulties regardless of the outside temp. Any ideas on the remedy? Thanks!
