i have an ‘08 LC. The seat heater switch failed and I installed an eBay replacement with no issues a year ago. I also had a rodent nest in the cabin air filter about 2 months ago. The truck hasn’t been driven much because there is a ‘14 LX in the garage which went in for some body work 3 weeks ago. The LC was bullet proof until yesterday when the seat heater switch light came on. Turning the switch on and off does nothing for the light. I am confused because the switch shouldn’t have power to light up unless the switch is on?
Then this morning I went to start the truck and the START button light didn’t come on and the truck was dead. Doors lock with the remote so it is okay but even when I held the fob to the button nothing happened. I got back home about three hours later, got the battery charger out and jumped in the truck to pop the hood and the Start button lit up and the truck started without issue.
Now I don’t know if the rodent caused damage or the cheap switch is somehow the cause or if it is a mysterious gremlin unrelated to the above. I have an insurance claim but if they can’t find rat damage I’ll be on the hook for the dealership bill which kinda scares me. Any suggestions?
 
FYI, turns out it was water from the plugged sunroof drains. Corroded wiring on both sides.
 
Open the sunroof and they are under the front on either corner, apparently there are two in the rear too. We (I am friends with the body shop guy) blew them out and poured water in to confirm that it ran out the bottom under the running boards.
 
BTW A great tool to clean out those drains is to simply run some line from a string-trimmer down them. Its strong enough to push debris through - yet flexible enough to bend in all the right places...
 
Not to hijack this thread but does anyone know of any drains in the rear hatch/lift gate? I've seen so many 100's with rusted out hatches due to clogged drains that i'd like to take care of these while i'm at clearing out the sunroof ones. Any other drains people are aware of?
