Thanks for those responses. I can rule out the kid factor, bad bulbs, and the switches on the fixtures, which leaves me with heat related overload at the fixtures, a possible switch failure at the wall, or defective light units altogether. That both lighting fixtures would fail at the same time leads me to a possiblilty somewhere other than the fixtures, maybe the wall switch, but the meter will find it. (just need to find the time to do it
I have had those fixtures replaced once already to remedy the issue of the plastic bulb covers falling off. But, with that fixture design, once those covers are removed, they never stay on again. Even the replacements have the same problem with that. If it turns out to be the fixture I'm going to replace them with something that looks better and is easier to service with bulb changes. Even though it's in warranty sometimes it's just a lot easier to order the part and do it yourself instead of having to wait 3 weeks for the dealer to get to it. And since we're in Kaufman it's a long drive to the N. Dallas dealership...and the Rockwall Dealership always seems to be backed up with several weeks of service...even to get to a ten minute job.
Last year our sink sprayer sprang a leak due to a split in the plastic handle and I ended up taking the parts kit they ordered home, after my AS sat in their lot for a month waiting for them to get to it, and replaced the sprayer nozzle myself....it took all of 60 seconds. You'd think these service depts would triage their service jobs to increase efficiency and flow their their service depts. duh.
