Replacing Heater Core on 99 Jeep Grand Cherokee

ralphlassiter · 02-16-2009, 06:02 PM

How do we get the heater and air conditioner housing out? Are there any hidden attachement bolts on the inside or engine compartment? We have done complete dash removal and cannot get the housing loose. Thanks for your help!

There is one bolt for the dash that is often missed and I do not think it is mentioned in the wjjeeps.com write-up.

You have to lay your head on the floor board and look directly up behind the dash. Then you'll see this:

Woops, sounds like you already have the dash pulled.

There is one bolt on the firewall up by the AC lines that goes missed. The other two I believe go in from the interior. The one outside is at the top of the box, and lust to the passenger side of the top AC lien if I remember correctly
