My 96 Sidekick Sport has a peculiar "cooling" problem. The car (now that it's winter, BTW) would warm up normally at idle but as soon as you drove it anywhere (especially at highway speed) the temp would drop to the bottom peg instantly. The problem was diagnosed by as a bad fan clutch. Both it and the thermostat (which was replaced two years ago) were changed. Problem not solved. Another (new) thermostat installed resulting in no improvement. We're waiting for a factory Suzuki part to arrive. Any other ideas?
Two, the drivers door lock tends to freeze. You can OPEN the door when it's cold, but you can't CLOSE the door. The lockinterior mechanism won't recapture. Short of pulling the interior panel and hosing the lock mechanism down with lube does anyone have any ideas?
