To keep, or not to keep; heater core, AC & blower motor..?

[DSMINMN]

I'm going to start with a little back information on this. When I received my '95 TSi the AC didn't work. I was fine with it as having the windows down is usually enough for me. I came to realize I had one AC line that was leaking and it wasn't even the correct one for the car! I removed it and capped it.

As far as the blower motor goes; there was a nasty stench in the car from sitting out in the sun for days. After taking the window cowl off I realized I had a mouse nest inside the car. After removing what I thought was all of it I left it alone. A few months later I took the car out and the smell was still there. I tried pulling out more of the nest from the AC box and it cracked a little. It still blew air fine so it didn't bother me.

Anyways, I put off the problem until this past summer. I decided to finally swap my interior from brown to black/tan. Since the dash was out I thought it would be the perfect time to remove the rest of this nest.

Just the other day I tried taking the blower motor and its housing out. Needless to say I screwed up the AC housing where the two meet. It made the crack quite a bit larger. Since that I decided to take all of the HVAC stuff out.

Now with the heater core bungs on the engine looped together I'm contemplating even putting the stuff back in. Then in the same instance though, I had a friend remind me about fog and such that would mess with my windows/windshield. I'm torn as I do not drive the car in winter nor do I drive it when it rains.

I'm hoping some of you who have removed your HVAC systems can help me decide which route to go from here.

Thanks!
