I watched these and I'm hoping this will help me fix my problem also...

 

I had exactly the same issue. I checked the AC blower mini fuse (25amp) and it was "blown". Bought a new one for .60cents, put it in and it works just fine...Sometimes it's best to look at the simplest things first!

 

I removed my condenser fan relay and swapped it with my rear window defroster relay, which is the same and the fan worked, so I decided to take apart the original relay and found that the contacts were corroded. Wire brushed the contacts and they now make continuity when they are closed. Reinstalled the original relay and A/C works fine. Here's the pics if you run into the same scenario. Easy fix.

the condenser fan relay is the middle one of the 3 large in the row.




This is the relay with the cover off, just pry four tabs and it slides off.




here you can see all the dark build up on the normally open contacts.




here's after cleaning it with a wire brush or something similar. After reinstalling it worked like a champ.

 

My 2008's fuse box does not look like yours. Do we not have a relay?

 

Mine is a 2004, I'm not sure about the 2008.

 

right. But where might those relays be? I just have a fuse box and no relays. I've check all the common spots for said relays and came up with nothing. Please help. I drive a 2006 ram 1500 laramie trim.
