Hoping for some insight or explanation ...

2001 base, over the winter my heat got worse and worse. Effectively blowing outside air in the car. Made for some chilly rides to work. Now that it is getting warm out, I've found that I have no a/c. It seems to blow whatever the ambient temperature is through the vents.

With the 20 year old car, I've had plenty of foam through the vents. I've been blowing the fan on high trying to get it all out.

I assumed that my blend doors had lost all the foam and that was why the climate control wasn't working. But, I don't see that related in many posts and can't quite explain how they would be related. Before I start tearing into my my dash or behind the battery, I was wondering if there was something else I should consider?

Does the loss of foam typically cause both heat and cool to stop? Is putting tape on the blend doors an actual long term repair?

I appreciate any knowledge. I want to start driving it again but at 90+ every day, it's too warm without a/c!
