AC intermittent issue
2001, 1500. AC Recent issues.
Issue 1. sometimes it stops blowing cold, blows warm or hot air. It does not go away so I simply turn it off, wait a few seconds and turn it back on and it starts cooling normal again.
2. also intermittently, it stops blowing air period, nothing out of the vents, it is temporary so i leave it on and on its own it starts blowing cold again after 7-15 second.
I don't really drive it all that much but would still like to fix the problem. I kind of suspect the AC/heater controller but what do you think? thanks

ok, the no blowing through the front vents happened this afternoon for about 4-5 seconds. i was able to put my hand on the defrost vent and i did feel cold air there. the blend door actuator was replaced some 7 years ago and it appears to be working normally otherwise -unless it is causing this issue.
as far as the other issue, where it all of a sudden blows warm/hot air it has not happened again yet. the above issue is the more intermittent one.

Finally got around to checking under the hood. The lower vacuum hose that goes into the firewall was not connected. Took a piece of rubber hose to connect firewall hose to the other end that was just hanging there. Went on ahead and tested both check valves while there and both were still good. Sadly, i have relegated the vehicle to a back up vehicle but it is still in great shape, everything works. As always thanks for the help.
