Ok, so i shampood the interior of my 89 S10 blazer with a 4.3. let it run for about 2 1/2hrs and "thought" it was all dry. Two days later went to start it and it just turned over....nothing at all.
I know its not from no fuel...(checked it)

Pulled the cover off the fuse box and it was covered in condensation. So i blow dried it till dry. Checked all the fuses (none blown) replaced the only two relays and still nothing?

What else should i do?

I also have put one of those pellet air dryer things on the drivers floorboard and left the cover off the fuse box..

I wanna sell it! but it needs to run!!

Thank you!

 

You let what run? The engine? Just idling? For 2.5 hrs???

Were the doors closed? If so, did you run the A/C the whole time? Heat only with the doors closed is not going to get rid of moisture. That's the why the A/C compressor runs when you turn on defrost, it pulls the moisture out of the air. If you just ran heat for 2.5 hrs with the doors closed, it just vaporized the moisture from the carpet and spread it throughout the truck, mostly the dash and electrical.

Pull the computer and check for moisture there.
