My 2006 hyundai azera limited passenger seat is locked in the down position. Any idea on how to fix?

You have the VIN#. Call the dealer. They are the only ones that can tell you your options on that car.

Bad motor

Seat memory control unit is faulty needs replacement

Check the spring which puts tension on the lever to hold it in the lock position this may have dislodged itself or be broken or possibly bent.

check fuse if not then motor is gone

Possible transmission gear noise, but would need to hear it to confirm.

I have a 2012 Azera and had the same trunk lock problem -- there is a security cutout switch located in the top center of the glove box opening which can be tripped if the glove box contents stick up over the lip of the opening. This switch disables the truck release on the dash and on the remote fob. On earlier Azera's the switch is located on the left side of the glovebox opening.

try fitting a NIPPON DENSO compressor as a replacement.hyundai is a copy of this unit.....

Take/Tow your vehicle to an authorized Hyundai dealership and pay the diagnostic fee... they will tell you exactly what the problem is and the cost of parts/labor to fix it... at least this way you'll know what the problem is and what's required to fix it.
