Greetings fellow DF'ers,
I finally got around to bolting on the TBS on Monday and, during the test drive, I noticed that the A/C fan doesn't come on. I know it worked the previous day and I'm thinking I must have jarred something loose whilst installing the TBS. I've done a thorough check under the hood and I've checked the fuses in the cab and under the hood but didn't see anything obvious.
Any idea what's going on or what to check next?

Thanks in advance,
-Jeff
