I know the common thinking is to replace the evaporator since you are in there anyway, but I don't subscribe to that. Unless it is abused or leaking, I don't see any reason to spend that money. I have had to replace my heater core once (less than 100k ago), but the A/C work just fine so I left that system alone. I didn't even disconnect the A/C hoses. There are a couple (three maybe?) vacuum actuators in there too you might want to inspect.

This job is such a pain, for the additional $150, I am going to replace the evaporator core as well. That said, in the first 5 years I owned the truck, I went through 3 evaporators. Dodge updated the design around 2001. My heater core started to leak, so I just blocked it off. In Florida, I can live with no heat, but no AC, now that's a problem. There have been a few high 20s and low 30s nights that put a chill on me. I have been waiting for the evaporator to go again before I change the heater core. 7 years later, (15 years total) the evaporator is still good and I still have no heat. Now I am going to need a dash too. I don't know if the newer high quality evaporator design has made its way to the aftermarket cores. I would purchase Mopar parts. Genos now sells them.

There is a company out there that makes updated blend doors/actuators that are more efficient in separating the hot and cold. It was not that expensive for out trucks. I cannot remember the name though.

There is a small cable that connects from the shifter to the gear indicator gauge. Be careful when dropping the steering column. I did not disconnect the cable and broke a small plastic tab. It's very fragile. Not a big deal, but one more thing I needed to fix.

I also had a problem with the condensation drain allowing water to run back into the cab. I put a small heater hose elbow out on the firewall and problem solved. I believe it was a 5/8 heater hose elbow.

Good luck and keep us posted.

The 'plan' is to remove the complete hvac plastic box and put it on a table and disassembling it. I could disconnect the dash and swing it back and tie it up on the passengers side. But then, I would have to squeeze in-between the seat, the dash and work on hvac system & I am not as
flexible as I once was. I would rather spend the time disconnecting all the electrical connectors on the drivers side and just remove the entire dash. Yes, it is a little more time(those darn chrysler connectors) but makes the job way easier.
Disassemble the entire box, clean it up, replace the needed parts, test actuators and door movement, while it is still on the bench. Sure it is more work but then you know for sure that every thing works as it should.
I have a manual transmission so don't have to worry about shift selector cable.
JMcoy,
If you remember the name of the company that makes those updated blend doors, please post it here. Dorman, maybe?

I overlooked the manual transmission. Lucky! I looked it up and think I found it. Heater Treater is the company. I believe it replaces the pivot point the door swings on with a metal one. Keep us posted on how it goes.
