sometimes when i try to lock my doors with the switch it doesn't. i then have to keep pushing the lock button and it eventually locks, what could it be. i have a 89 7mge switched to gte.

If the mechanism works but is merely really stiff, the old grease needs some help. Try taking off the inside door panel and spray down the mechanism with good spray lube like Tri-Flo or Super Lube. It's kind of a pain to get to it all, but a full can with the long spray tube does work.

After 20 years, the factory grease gets hard. It may even take a week or so after respraying for the new spray to soften the old hard grease.

Do they go to the lock position the back to the unlock position? Mine do that sometimes.
