Sometimes the switch for the sunroof/moonroof will operate the panel properly for opening & closing, and also for the vent position raising & lowering.
But sometimes the switch will seem like it's "dead" and it won't operate it at all. Naturally, this happens at the most inconvenient times.
I know that newer Grand Cherokees (WJ & WK) can have their sunroof systems re-calibrated, but I don't know if this type of calibration applies to the ZJ model.
Anybody have any input?
