I am in the planning stage for pulling the dash apart on our '98 Tahoe. The dash in in great shape but have really poor airflow and have to assume the AC evap is plugged up. Also, the AC is non-op but not sure what the issue is- I suspect the AC evap is a likely culprit for my freon leak but haven't loaded the system with dye to check. I'll tackle the AC problem soon and have a feeling it will get to be a royal pain but the evap looks to he the biggest pain.
My questions are what would be smart to check/replace while I have the dash apart? My thought was on a 16+ year old vehicle since I am pulling the crap apart and don't want to do it a second (or third) time, I was thinking:
- Replace the AC evap
- Replace the heater core
- Clean and inspect the firewall and behind the dash
What other items are common failure items that require the dash to be pulled? Don't want to send the wrong signal, I'm not throwing money away by replacing a bunch of stuff for the hell of it I just would rather hit the usual suspects when everything is pulled apart.
Another issue I have noticed but not sure if it is dash related it the fuel gauge and oil pressure gauge both "buzz" and by that I mean the look to vibrate. They indicate and track but they should not buzz like they do and not sure if this is a loose connection somewhere that I could address while I am taking stuff apart...
Thanks!
