just got a 89 4.0 auto with 256K miles and the AC/Heater is not blowing at all

when i turn ac on i hear the compressor turn on but nothing blows

i checked the fuse under streering wheel and its not blown

any ideas what i should do?

 

blower motor, open the hood and run direct power to it to see if it comes on, if it doesn't that is more than likely the problem

 

how do i get to the blower motor? do i need to pull the dash?

 

no sir, open the hood, it's right behind the washer fluid reservoir, not had to get to at all, then disconnect the plug and a connect 12 volts directly to see if it comes on, also it could be the blower motor resistor thingy (don't remember the actual name) this is under the dash on the passenger, i think it's called the BCM, it could be corroded. try the easier of the two and work to the hardest

 

ok thank you!! i found the blower motor but where is the resistor? any1 gotta pic of what it looks like?
