Hey what's up guys/ladies, I am here with my issue of the week lol my heater/ac isn't working all that well and I have no idea why. It seems to start blowing once the truck warms up but still not very heavily, like almost non-existant. Anyone know why? I thought maybe the AC just needed to be recharged but as far as I know that wouldn't affect the heater. Help please!!!!!!!! Oh and it's a 05 Silverado with the 5.3. Worked fine when I bought it.
