On longer trips usually lasting a few hours or more, my AC fan loses some power. It still blows cold but blows with barely any force. Then it will come back to propose force usually within an hour or two. My truck doesn't seem to lose power while that happens. Just the AC blower. What could be the cause?

Try this thread. Seems like other doge owners have your problem or similar.
TLDR: some of the problem lies in the compressor clutch solenoid, when the amps drawn is too high the computer then defies logic and turns off the compressor even if it's 90 degrees outside. Others also point out that for whatever reason replacing the compressor was also a fix. One guy in the form said that after multiple testings, the vent solenoid motors were to blame. The first two are the most common it seems.
Thanks! I'll give that a shot
If you turn off the AC, does it have any effect on the issue?
Yaser: I haven't tried tuning off the AC. I've turned off the fan and that hasn't resolved the issue. Seems to do it only during warmer outside temps.
