PostSubject: Sliding Door Goes nuts in hot weather!   Sun May 29, 2011 12:05 pm

Hi All - My sliding door has started playing up when it gets hot (ususually after its been in full sunlight for an hour or two).

When i shut it the electric closing mechanism goes nuts and cycles about 5 or 6 times and then sometimes stops in the wrong place so that i have to squeeze the door handle and release to let it sort its self out before the door will open again! - it works fine when its not been cooked in hot sunlight.

I presume this is due to the door expanding when hot and the mabey going out of sync with the door lock?.

Has any one else had this problem, and any ideas on how to adjust/fix it?

Thanks

You are probably right...
Maybe try some wd40 on the sliding switches and then ensure the contact surfaces are cleaned up...wire wool etc.

the electronic lock on my SC sliding door has malfunctioned a few times like yours. It was because the wireless lock (remote key entry) had to be reset for the sliding door> I did this by manually locking and unlocking the sliding door. Also once in cold weather the door would not shut at all. The locking mechanism was seized. So I put wd 40 on it and then greased it and held it in with a bungee tied around one of the headrests and and after a couple of hours it was fine.

Not sure if this helps as hot weather and sunlight was not the problem. However DRY cold weather was a factor in the lock seizing.

Cheers for the replies - Will definatelly do the manual reset thing, and if it does it again I'll try it while its playing up to see if it will reset to a different position and still work when its cold - thanks for that.
Don't think anything is siezed and I keep the locks greased and the contacts clean so hopefuly it's not that.

Finally found the problem - it turned in to a permenant fault a couple of weeks ago so i could find it properly.

There are two switches on the door lock for the final closing motor (one to tell it the doors just been shut and one to tell it that the motor has done its job (one revolution)) and a circuit board to run the system (toyota call it a relay) - there was no voltage going from the circuit board to the switch that tells the motor to stop after one revolution so the circuit board had stopped paying attention to the switch so it just kept going untill it timed out in any position it pleased!

The circit board is in a small black box on the back of the door catch so you have to take door card off and the catch out to change it but its quite an easy fix.

Circuit board (Relay) cost 47 from toyota.
