86 GL wagon

 

So yesterday I was driving down the highway and I was switching between the defrost and vent heater. Well I clicked the ac and then defrost and then it was like blowing out both the defrost and the vent and then it just stopped blowing all together. I notice that my guage for adjusting the temp (the blue to red throttle thing) will only go down like halfway now. I turned off and on the heater and nothing happened. I turned the knob from 1-4 a few times and nothing. Well this morning I turned on my car and it was blowing again. The problem is that it is cold, or not very warm at least. I stuck a knife in to pry the heater (blue to red) thing up all the way and it seems like it got a bit warmer. Any ideas on what is going on here? Did a cable break behind the dash or what? Great time to go out out...been in the single digits here for the past few days....haha

bump- any ideas?

could be a condensation build up and froze. mine has done it a few times. i usually leave it on the warm setting and while it warms up it'll start moving. i plan on pulling the dash aparts and soaking it in WD40.
