Not blowing, not getting hot, not adjusting air distribution to where you would like it? Love to help you but a little more to go on please.
Not getting hot blowing cold air
There several things to check first, Is there coolant? is the engine getting warm/normal temp? If there is coolant and the engine is at opperating temp do both of the hoses to the heater core get hot? Is one of them hotter than the other by a considerable margin? Now if all of these are okay then you will need to check the temp blend door function. Have you been hearing a terrible clack clack noise from under the dash? Lets see what you have now before going any further.
Same problem with me. Actually just fixed it after thinking it was the blower motor. It actually isn't, it's the blower motor resistor that you can buy from parts store for $20.00. Actually very easy to put in. If you need help you can email me firstname.lastname@example.org
Therealjake not blowing hot and not blowing aren't the same. If it blows on 4 but not 1 2 3 then its the resistor. I'm glad that you were able to repair yours without much expense.
