Re: climate control problem
Is the coolant level down? This can cause a no heat problem. Anything changed or unusual about engine temp, (high, low), or how long it takes to warm up? If coolant level is ok, let me know about engine temp - warm up time.

Levi, If you have the same climate control, then below is a link to a repair video for your climate control. Sorry, this is the part 3 video, look a the side to find the part 2 video and watch it first.
I have a 2000 pontiac grand prix with a digital climate control system.
The heat quit working, it doesn't blow out any heat. Now that it is warm
outside the air stopped blowing out any air. The digital temperature on
the climate control is not correct. When it states that it is below 30
degrees on the ext and it is warm outside the air wont be cold. Once it
starts going above 30 degrees the air gets colder. Today the blower stop
working all together. Was told it maybe the climate control unit was
bad. You can hear the door opening/shutting when you switch the temp
from cold to hot. But there was no heat blowing out whatsoever in the
winter time. Could you please give me your opinion on whether or not it
is the climate control unit or something else?
That sounds to me like your vent "tubing" is disconnected somewhere along the line. I am not sure exactly how it is set up in the vehicle you are driving, but I am certain fixing it will involve taking apart most all of your interior then putting it back together after a 10 minute fix.
Ok it may be that the heater core bypass valve isnt opening. All that valve dose is when you turn the climate control to heat it opens a valve that allows hot coolant from the engine to flow through the heater core. What I would do is check that. It will be on the left side (passange) of your engine bay.You will see two black coolant hoses next to eachother and one will have a black box with a wire that runs to it. Have someone move the climate control from hot to cold to hot back to cold. If you dont see the wire move then you can move it yourself to open the valve.
Let me know if the valve opens or not using the climate control.
