2004-2008 Pontiac Grand Prix: How to change heater core

Thu, 08 May 2025 08:16:36 -0700

My passenger floor mat is being covered in coolant and it is coming from behind the dashboard where the heater core is located. I would like to know the proper steps to take in order to remove the dash, like what exactly I have to remove, and how to remove it so I don't remove anything unnecessary. I also would like to know how the cover for the heater core inside of the cabin would come off because from what I can tell there are plastic rivets holding it in place

2004-2008 Pontiac Grand Prix: Anti theft system/Lock system, stuck in learning mode

Thu, 18 Apr 2024 05:59:34 -0700

So I got an 05 grand prix, the theft system is in learning mode and I can start it, though I only have the valet key for it, I assume if.i just do the learning procedure it will take it out of learning mode though, I haven't tried it cause I'm not sure if my key will start it if I do and I'm not ready to pay for that headache , unless itl be fine if I do take.it out of learning mode, also having issues with the door lock switches only locking the doors and the trunk release won't work either cause it's part of the lock switch, but putting it into drive locks and putting it into park unlocks them just fine.
