Does anyone have any information, or maybe a PDF for the removal and replacement procedures for the AC evaporator on a 1999 Dodge Ram.

Just want to know what is involved before I tear into it.

Thanks in advance.

 

Not an easy task. I replaced mine in a weekend. I would search on the internet for pdf drawings or a detailed repair manual, Autozone, Napa, Checkers, but make sure its detailed. I was quoted $900 for the repair and was not about to pay that. Parts totaled around $260 I think, more radiator fluid $10, new hoses $10, re-charge $80, evap. core $140, manual $20, etc. Before you start make sure the a/c system is drained, should be already I assume. Drain out some radiator fluid, remove hoses from heater core and a/c lines in the engine compartment, as well as nuts holding on the heater box. The dash is tricky, the glove compartment comes out, ashtray, lots of wiring gets unplugged, I can't remember everything, and there are two bolts under each side that go into the "A" piller, these just get loosened and you will want to pull the dash up off the passenger side bolt and use a tie-down strap to hold it up on the grab handle. THE DASH DOES NOT COME COMPLETELY OUT, unless you want to unplug ALL the wiring. Its not difficult to do just time consuming. When you pull out the heater box it splits in two by removing the bolts, evap. core and heater core sit parallel to each other, you can tell its shot if there is fluid in the bottom of the box. Now, I live in a warm climate and I did not replace the heater core, even though my truck had around 150K miles on it. I inspected it, ran water through both ends to flush out any debris, and it was fine. If you do live in a cold climate and need heat in the winter, I would replace it while the heater box is out, Autozone has it for $75, cheap insurance. Good Luck with your repair.
