No heat or AC in a 99 RT/10

[moparguy]

I'm hoping there may be a simple explanation for this one. I can't get warm air out of my heater, or cold out of my AC. The fan just blows ambient air thru the dash vents at all settings. What should I look for?
Thanks!

My old 99 did the same thing after awhile. Dealer had to replace the ac lines. Worked fine then. Tech said this is common.

Check controls (temp cable). I'm sorry I can't remember what the control panel looked like inside the dash. Guessing cable slipped off. I don't remember if there was vacuum controls or not (open-close doors inside heater). Since your fan is working it's not likely to be a fuse. Look around in the passenger footwell and see if anything is loose on the heater. When you turn the temp knob there is tension?

If you don't have one, buy a Shop Service manual so that you can 'see' inside without taking things apart.

Call me for some of the "simple" things to check for both modes.
