Complete hvac removed need holes plugged

[bradselph]

I removed the heater core, condenser and blower so there is nothing under my dash but I'm left with the holes in the firewall, what can I use to plug them holes?

I've seen kits of various size rubber plugs. You should be able to get them at any parts store. Unless you need something more permanent. You could bondo and paint them.

I figured thats what I would use for the 2 or 3 round ones but there's the big oval one were the ac came through that's got me wondering the most.

Kinda wanna avoid the bondo and paint until later on down the road.

Wow you got that right, i never had any idea mitsu made rubber plugs ffor all that stuff. I had the heater core and everything related removed in my 92 laser and left and holes open and just ignored the air blowing in, since it mainly effects the passenger side seat.
Good to know these #s, since im planning on pulling the core from my talon i currently have.

How about a plug for where the engine harness comes through?

There's not on that I've found. I'd like to fine one so I can block mine off since I've got a cannon plug now.
