This sucks. It's the rainy season and i dont have any heat to defog my windows. Has anyone diagnosed this problem yet? What are the solutions to fixing it? My heat will not work on any of the speed settings.

do you mean your blower will not work? The blower works and there's no heat?

Coolant system level ok? Low enough level can cause unheated air to blow, even w/engine fully warmed up.

the blower is totally dead. nothing is coming out, hot or cold.

the a/c is broken, but thats not my concern because i dont really use it. but the heat is nessicary for where i live.

No blower in NH in the Winter, damn that is brutal. You might need one of these. The actual blower motor is in that round housing at bottom of pic.

Test your blower and make sure its gone before ripping it out - lots of people have had problems with the switch itself and not the blower.

You have a 92 which means you have the cable driven switches for vent selection and fan speed. My cable slipped out of one of the clips once and it wouldn't change vents. The cables need to be held in certain spots so that when you move the switch the tension doesn't just bend the whole cable, but rather forces the cable to slide inside the sleeve and move the mechanical section on the blower.
So it could be-
1. Cable is broken or off at the switch
2. Cable came loose from the clips that hold it in place on its way to the blower
3. Blower motor is worn out
I would check them in that order too since they are listed from easiest to hardest to fix.

I had no heat once, it sucked!! I took it in to see what it was and my mec. slid his hand down by the blower and put the hose back on and put a small screw in it to stop it from happening again! he said it is easy to kick it off if you have tall passengers! I felt dumb, but I was warm! give it a shot!
