I had bout forgot about this thread. LOL. I've been tinkering around with mine. I put the blower motor out of my parts truck in it. That helped a little. I took it back out and tried to wash the evaporator coils out with my water hose the best I could. That helped some too. But the biggest problem I found and fixed is the plastic housing under the hood that holds the A/C system is a two piece affair. Mine was split apart at the seem slightly and blowing cold air into the engine bay. I sealed it back up the best I could with some black rtv silicone. That helped some too. Turn your A/C on and run your hand around the housing at the seem, if it's leaking you should feel the cold air coming out under the hood. I am still looking for a better blower motor as I'm still not getting near the airflow out the vents my 96 has. I just don't have much time to mess with it here lately.

 

does it blow harder when air is sucked in from outside? if so maybe something from the glovebox is trapped by it

 

They are dicussing this same issue on the big bronco forum. Greystreak has suggested useing the squirell cage from a newer year car/truck. It seems that they have made advancements in the fan design.

 

well try contactin red dot.

they make after markest ac products

 

I worked on my ac today having little success with air flow. I came up with a last resort before piling my dash. I removed the trim bezel, plugged up all but the second vent from the drivers window. Through this port I inserted a 5gal vacume hose that I had hooked to the output so it would blow. I inserted the hose and routed it toward the third port then down just before the opening then blocked everything off as air tight as possible. I ran the vacume, blowing, for 15 minutes. Turned it off to cool then repeated this procedure several times throughout the day. It actually helped. I believe if I repeat this a couple more days I might alleviate my problem. This is not a perfect fix but it seems to work!!
