Heat comes and goes , takes along time coming and blows cold air @ my feet all the time. Someone said vent might be stuck open; how do I get it closed? Any and all advice welcome, thank you in advance. per

Sounds like your thermostat is trying to go bad, and the vent seems stuck open.

Not sure ont he vent, but the thermostat is an easy fix and less than $10.00

turn your defrost on if cold air stops at feet your vent is not open. is your temp neddle moving if not ?

Thank you for your help; with defrost on no cold air comes on @ my feet, and yes temp. neddle is all over the place. New thermostat needed?

Ithink your right about the thermostat the temp. needle moves all over and the heat seems to come and go. I turned on only the defrost and the cold air @ my feet stopped as login suggested. THank you for your help.

Your temp gauge will also fluctuate if you have low coolant, or air trapped in your cooling system. If your thermostat stuck open the car will never get hot, if your thermostat is stuck closed your car will overheat. To test your thermostat, drop it in a pot of boiling water (don't use your wife's good pots, I guarantee you'll get in trouble), it should slowy begin to creep open, until it reaches the stop.
