I like brum brum
Your clutch is not disengaging.
on a 2000 intrigue; car does not shift into 3rd gear or 4th gear. 1st 2nd gear ok
If the shifter will not move you have a mechanical or electric issued with the shifter. If the shifter does move you may have low fluid or a failed transmission.
You have a faulty gearbox.
Double clutch then go to 4th gear then go for it.
i haven't had problems with my 98 reverse, but my other gears have acted up. i believe that it might be the syncronizer. i sometimes cant get in 2nd or 4th gear. i have to shift it back and forth to work it in. SO, i might be having the same problem. a mechanic told me to either change the transmission fluid or to go ahead and get the syncronizer checked out. i haven't had problems with my 98 reverse, but my other gears have acted up. i believe that it might be the syncronizer. i sometimes cant get in 2nd or 4th gear. i have to shift it back and forth to work it in.

The locking mechanism controlled by your break pedal has failed. Call a shop
I Think you should go to a mechanic
Most likely a broken gear cluster
Check if the clutch is working properly.
Switch to 4th gear!
that usually indicates a vacuum leak which causes the system to go into default mode, which is defrost.
