Heater box cleaning


1986 Grand National
Greetings all,

How much of a pain is it to access inside the heater box ? I want to clean the heater and AC core for better air flow.

There are a ton of little screws and a couple of larger ones but it's not too bad. You have to remove the blower I think. I took mine out to clean the condensor and it was not horrible as I remember. Use a little sealant when you put it back together. Make yourself a diagram so you put all the screws back in; there are some that are in unusual spots.
