1996 C4 A/C Dash Vents

My 1996 C4 is not blowing air through the dash vents.
Below vents and upper dash vents are working OK, blowing air.

I have been hearing that the problem could be the three
way check valve.

Does everyone agree?

If so, how hard is this to fix?

Thanks,
Bill

That's a very common problem on '96 models. Check this out link. This made my vents work perfectly. No more problems.

usually it is one of four things: the 3-way check valve, vacuum lines in poor condition, the programmer vacuum tips, or the programmer.
