The Sunroof on My 2001 GS430 is stuck it will only move up and down but it struggles too. I even tried taking the motor it’s self out and cleaning it and still nothing, the gear itself spins fine on the motor but when i tried to hook it all back it still just doesn’t open only moves up and down but barely.
