"99 Jeep cherokee 140K miles great condition, had tune-up spark plugs, oil etc. no problems. heat worked good, however AC dosent blow out cold air very weak....bought some anti-freeze still not cold air.....should I purchase some free-on and put it in? dont kno whow to put it in so I would greatly appreciate any suggestions or step by step instructions....here in Jersey we have had 100 plus days and I need the AC for the remainder of the summer ....please help thanks....

 

Can you hear the the AC running but no air really comes out? or does warm air come out? if your AC is turning on but you're not getting air flow, it is probably your Heater Blower Motor Resistor. use the search function and check youtube, lots of write ups.

if your AC is blowing but its just not cold, you probably need freon.

 

I will try it again, it blows really low air not really cold air like the newer cars do....even when i turn it all the way up....the heat is strong but not the AC? how do I put the freeon in?

 

You're probably better off to take it to a shop.
