Buick Reatta Service Highlights
This is probably the best Reatta video I've seen. I learned a lot about my car I didn't know by watching it. The first part tells about how the Reattas were built. The second half gives a lot of technical tips that I didn't know about. The video is kind of long but you have to watch the entire video to get the most out of it.
Rock Auto for one source or the salvage yard. It's called a blower control module/resistor. I would jumper power directly to the blower motor first to be certain it can actually run. It is on the engine compartment side of the firewall, on top of the blower duct toward the passenger side.
How to Test and Find a Parasitic Battery Drain (Key Off)
Although this isn't Reatta specific I'm posting it because it is the best video I have seen that shows how to troubleshoot a car using a multimeter that has something draining the battery. There is also a tutorial here on ROJ in the How-to section that shows how to use a multimeter to do the same basic tests on a Reatta.
How the Teves ABS system works
This is a good video that I found on YouTube that gives a good description of how the Teves MK-II ABS system works. It is on a Chrysler vehicle but it is the same ABS system that is used on the Buick Reatta. You can learn a lot from it.
Super Clean Your Windshield with Steel Wool
I found this video on another forum. Several Reatta owners have reported that this method for cleaning a windshield works well.
