I'm replacing the heater core in my 1994 dodge Caravan. I've ripped the dashboard apart and all the metal bracings as well as the nuts on the engine side of the firewall have been removed, but there seems to be something still holding on behind the steering wheel that I cannot get to or find. It seems that the entire dash has to be removed and the HVAC box will come out with it. If there is an easier way to remove the HVAC box without taking the entire dashboard with it, please let me know!
