Within the last year or two I have noticed that regardless of the weather or temperature setting on the climate control that the air blowing out of the vents fluctuates from time to time. During the summer months with the A/C on I get random warm air. During Winter months, random cool air blowing. It doesn't happen long enough to really effect the temperature in the truck but when the vents are blowing directly on you, it's kind of annoying. Any ideas?
I've thought maybe it's the heater core but wouldn't that blow constant cool air during the winter months if it was clogged? Would the heater core also affect A/C?
Any thoughts?
