Glad that you got it working again. Let us know if you find the original source/root of the problem. I too suspect that the vehicle has been flooded in the past.

 

 

My car sat for a while i was working on my project car, 77 corvette. The lexus survived hurricane irma last yr.

 

 

Everything works, only the blower did not. So weird. Went crazy going through all the fuses. It was a great learnjng experience

 

You can get some electronics cleaner and spray it on the block to see if it will help.
This is the kind I usually use,
But they also have this more expensive brand which seems better
The blower MAY be the FIRST piece to be effected, so a contact cleaner is something good to have on hand.

 

Did I read somewhere the SC has a condensation hose that sometimes leaks inside the cabin, or was that another car?
