I have a 2004 CTS. I know there are two fuse boxes underneath the floor carpeting in front of the rear seat. Remove the rear seat bottom cushion and pull the carpet forward and you will see them. Inside the cover identifies what fuse is for what function. Hopefully it is a blown fuse, otherwise my guess would be a short in the wiring some where.

Check for coolant in the oil. The oil will look like chocolate milk. After it's sat overnight you can also try loosening your oil drain plug until fluid comes out. See if it looks like chocolate milk or is just straight coolant. Check your spark plugs. Pull them out of the cylinder head and check for white corrosion or actual coolant in chambers or threads. You can also do a block test (rent the block tester at Autozone for $25.00- return when you're done and you get the $25.00 back) the block test fluid is $8.99. Follow the directions and if your test fluid turns green or yellow you have combustion/emission gases in the coolant. This can be caused by a cracked block/ cylinder head/ blown head gasket. You can also disconnect one head's spark plugs and test that cylinder then the other to see if only one is causing the problem. Hope this helps. If you're losing coolant, it's probably not your water pump. A lot of times if a head gasket fails, the head (usually made from Aluminum) will crack or warp.

No fuse.These seats are protected with relays and a seat module.The module is under the drivers seat.There are 3 connectors and it would be hard to check all these wires for power to the motors.First look under the seat and make sure none of the connectors came apart under the seat by something that might have been left or rolled under it.The 2 main ones you can check are the connector 2 terminal C and connector 3 terminal A.C is a black wire which is ground and A is a red wire which is the feed power wire.Connector 2 is green and 3 is black.If the ground and power wires are good then you could have a bad drivers seat module.What I would do is go to the salvage yard and find a used module to try.Good luck.
