How do you fix a front passenger seat stuck in recline for a 1991 BMW 535i?

The same thing happened to me mate, After removing the seat from the car and doing various tests I had a fault with one side of the seat. The bad news is the closest I could get to a full diagnosis was a fault in the gearing or the cable that runs from the motor to the gearing. I was told that you could not replace individual components, so i would have to purchase the motor/cables and gearing and the only supplier of the complete unit was BMW dealerships (costly). If your seat is still knackered I sugest that you look into picking a whole seat up from a breakers.

Bridges Breakers quoted me £40 quid and that was for a leather seat.

Good luck
