Two little problems (odo and a/c)

Synned said:

I'm pretty sure I know the problems but I want to make sure.
1. The odometer stopped turning. The speedo still works, but the odo or trip meter do not spin.

2. The A/C Is on and off between blowing through the defroster or the vents - sometimes it goes through defroster, sometimes through the vents.

For the odo, I guess I have to replace the gear inside the panel, right? Because if it was the sensor in the trans wouldn't the speedo stop too?

For the A/C I guess I just have to look at that small vacuum line on the firewall.

Thanks guys
Joe
