Firewall access on 97 jeep grand Cherokee sport
I need to drill a hole thru the firewall to replace a
freeze plug I cant figure out how to get the ac duct
What?????? That's not right, hope this is your own rig and not someone else's your working on. To get the duct work you have to remove the heater assembly, to get to that you have to remove the dash. they designed it that way, if you do take it out better replace the heater core while your there. If you got one freeze plug leaking the rest aren't far behind, best to pull the engine and replace them all right along with any seals that look like they are seeping.
