89 Dakota 3.9. Well, I got the dreaded Freon leak in the ac evaporator. Not looking forward to this. Any tips, strategies or instructions would be appreciated.

Make sure the heater core is good, while you have the box down. If the heater core ios original, I think I would replace it along with the evaporator. Gene

Can't offer any advice on an 89, but on a 2004 Dakota....I had to drop the whole dash to get the heater/AC box out. I was doing the job the opposite way, with a bad heater core. I dang sure wasn't taking a chance on having to do it again, so I replaced my evap core while I was in there. If it has electrical door actuators, note what the dash control setting is when you take the box out, and take pictures of each actuator position before disassembly. That will save a lot of head scratching when you put it back together! Best of luck to you.

on my 92 you need to remove the lower part of the right hand dash,normal wires/vacuum lines,about 6 or so nuts on the firewall side and the complete heater/ac box comes out on the passenger side


my ladder of success is missing some rungs
