'04 GT Heater core
Newbie question for a job not fit for newbies.
I have an '04 GP, 3.8L 110k - heater core leak. I've read a number of forums and instructions on how to get at the heater core. I'm working my way into the heater core, and it looks like there is no way to heater box except by pulling the entire dash, contrary to all i have seen. Am I right on this? The glove box does not open to boot, making removing some of the trim impossible. Any suggestions much appreciated. I've pulled the lower and center consoles and left (US) trim. Cheers, dave |

Re: '04 GT Heater core
Hi Oscar,
thanks! I have read this as well. Unfortunately after pulling the consoles, and the trim i get to a point where i can see the heater box behind some bracing. It looks like the bracing is in the way of the heater box, and the bracing is part of the dash. Unless you get at it from underneath? I spoke to someone who was a GM mechanic a while ago and he suspects the dash has to be pulled and the AC drained to do it right. I was hoping for a work around, outside of bypassing the core:-) I'm going to try to get at the glove box tonight and get it open so i can pull the rest of the RH trim. This is likely to wind up at my local mechanics tomorrow or Friday. I will post what I find out. Thanks again. Dave |
