Well some updates, I put a new blower motor on it and when I turn it on it kinda sputters now with the new one on it, I double checked everything and the resistor is good everything is getting power just not blowing air, I used the old white fan from the old one as I couldnt shell out 35 bucks at the time to get it both, so do yall think it could be the white piece in the blower motor?

Maybe the motor turning but the fan is slipping. If you remove the motor from the housing and keep it plugged in. Then have someone hold it and someone else turn the fan on and see what happens. The fan part wasnt broke or anything was it?

no the fan looks new i checked it out before putting it all back in. should I get a J.Y fan part and test it? if it is working what else could be the prob? I doubt the vents are clogged

well now I smell a kinda coolant/ burning smell from the vents, the fan motor is working cause I have heat flow throw when I go down the road ( like before) just nothing when I sit still.

So ive been reading some fourms here and ive herd that people are having the same problem with a air mix actuator, and its suppose to be under the dash?? is there a way to test that is it, im running just about everything I can to find this problem and come to dead ends.

checked the air mix it was good, and now that I put it on normal from the AC side it blows cool air it never did this before with the other blower motor, so i assume we are getting in the right direction. But it still wont blow anything sitting still..I was thinking could it be a compressor?
I'm getting power to all my stuff and is working but not blowing this is so mind boggling. And with summer on the rise I will not be sitting in 100+ degree weather in florida in a hot car haha.
