Default Air conditioning cuts out

I have found many threads about A/C issues but have not found this issue described previously. On my 2010 4.0 awd with approx 16000km the A/C exhibits the following:
- towing for approx 1/2 hr (not consistent)
- A/C on entire drive (max or normal)
- mainly highway driving
- any fan-speed

Air flow stops/very low. The fan can be heard but there is no airflow from vents, floor, defogger.

Shutting of truck for a few minutes resets and A/C runs normally.

As this is not easily replicated I doubt the dealer will be much help.

Has anyone experienced this or have a starting point for me to be able to replicate for dealer?

Thanks in advance

I think it may be something along these lines. I plan to follow up with the dealer and will share results.

could be freezing up from the cold air....i've seen it happen
thin frost build up on blower stops air flow....shut it off for a few min, it thaws....then youre back in action

Thanks for the info. This makes sense to me. When I park for 5 min there is a lot of water from the condenser.

Found a thread on the equinox forum where the problem was traced to the system freezing up. Still haven't made it to the dealer yet but as the humidity is gone the issue has not represented itself.

YES!!! I have experienced this too before while making long road trips! I have never given it much thought, I just turn the ac on and off a few times and it comes back on.
