The noise is most likely the drive belt. On that year and model, you have 3 different drive belts: one for the power steering, one for the alternator, and a serpentine belt for the rest of the accessories. Based upon your symptoms, the alternator belt would be suspect. But in this case, the alternator belt is a secondary belt powered off of the A/C pulley. So the culprit is most likely the serpentine belt. Cheapest solution is to replace the serpentine belt and see if that resolves the problem. If the problem persists, then the automatic belt tensioner for the serpentine belt is the next most likely culprit. This is a royal pain to replace and just the part can set you back in dollars. I've attached an exploded view of the right engine mount -- you will need to remove most of this in order to access the tensioner. Good luck with that!

I have a 1991 tempo and the vents on das h don't work defroster and heat to floor work great but not the vents

All the vents are connected, a vacuum controlled flap diverts the air to each area.

With that said I would say that either the vents are obstructed by something like a rat/mouse nest or that your vacuum controlled flap is stuck or does not have enough vacuum to move it.

A vacuum leak will sound like a constant hissing sound.

I removed the air unit on my 1991 Ford Tempo, Need What Belts?

I think the belt for the a/c runs only the a/c compressor. There is an automatic belt tensioner on a separate pulley. So, if you just have the a/c pulley and the tensioner, you can just leave the belt off.
the alternator has it's own belt.

Location of auto trans dip stick on 91 Ford Tempo 4 cyl.

It's right next to the air filter and behind the radiator fan and to the right of the oil dipstick. The transmissions is black and the oils is yellow. If it's a manual, there's no dipstick there. If not check close to the forewall towards the back of the engine.
