The front passenger seat doesn't recline. The handle seems to work perfectly

use a meter and test the switch and motor

Question edited for clarity and errors.
Question moved from Seat, (Spanish car company) to PT Cruiser.

You would be better to fly, or put her in the back seat with lots of pillows and use the centre lap strap as a seat belt.

If you pull the seat all the way forward and remove the headrest, you should be able to see the maximum recline, but electric seats have a stop on them.

try sliding seat all the way forward and then back then try pulling the handle to recline

I usually find coins or something similar jamming the mechanism. Does the recliner handle move freely and travel completely?

It sounds like the inside of the recliner knob is stripped out. If you go to your local GM dealership and give them your VIN number they can order you a new one. Here is the removal and installation directions.

2010 Equinox drivers side won't recline.
Found the cable popped off recline mechanism.
Pulled back the lower seat panel near the recline lever after removing one torque screw located on said panel which is on the back of seat. Works great now. By the way, Freedom Chevrolet in San Antonio, Tx, without diagnosis, wanted to charge my girl friend $860 to replace the whole assembly.

On W-Body vehicles, the front seats are secured to the floorpan by two front hook attachments and two rear bolts installed to nuts welded to the floorpan.
The manually operated two-way front adjusters provides only fore and aft movement of the seat. When the seat adjuster handle located on the front seat is pulled up, the seat adjusters unlock, permitting travel of the seat. When the seat is in the desired position and the seat adjuster handle is released, the seat locks in place.
A power operated six-way seat adjuster is available. The adjusters are activated by three 12 volt, reversible, permanent magnet motors with a built-in circuit breaker. The motors are energized by a switch bolted on the seat side panel.
The three motors drive the front seat and rear vertical actuators and a horizontal actuator. When the adjusters reach the limit of travel, torque is absorbed through the rubber mounted grommets located between the motor and the support. An overload relay is provided in the circuit and will open should excessive stall be applied.
The optional 60/40 split bench front seats have seat back head restraints on the driver's and passenger's seat back. The head restraints are designed so they cannot be removed from the seat back without first inserting a small rounded tool inside the head restraint support tube to release the locking tab. The 60/40 split bench seat is equipped with a reclining mechanism on both the driver's and passenger's side. The recliner lever is located on the outboard side of the spring cushion. When the lever is pulled upward, the spring loaded dual linear reclining unit located in the cushion frame is released, allowing the seat back to be pushed rearward or allowing the spring loaded reclining unit to bring the seat back forward.
Bucket seats are equipped with manual reclining mechanisms. An optional six-way power seat adjuster is available. Some bucket seats are equipped with inertia seat back locks. This system allows the seat back to fold forward without requiring the occupant to release a locking lever or access to the rear seat area. During a sudden stop or deceleration, or if the front of the vehicle is nose down, the inertia system of the seat back lock will engage, holding the seat back in its rest position. A release lever is provided to allow manual release of the seat back lock when the vehicle is in the nose down position. The release lever is located at the lower rear outboard corner of the seat back.
Some W-Body vehicles (notably Pontiac coupes) have passenger front seats equipped with an E-Z Entry device. This is actuated, in an unoccupied seat, by completely folding the seat back forward disengaging the adjuster, and sliding the front seat forward to gain access to the rear seat area. To return the seat to its normal position, return the seat back to its rest position, and slide the entire seat rearward, engaging the adjuster.
W-Body rear seats are available in several styles including a rear seat with an integral child restraint device.

I TAKE IT YOU CAN'T USE TILT ON YOUR SEATS MOST LIKELY TO BE BROKEN CABLES YOU WILL REQ CABLES & BOTH SEAT HANDLES TO DO JOB OULD NOT RECOMMEND IT THOUGH AS ITS A PAIN OF A JOB TO DO.RECOMMEND BOOKING INTO LOCAL FORD DEALER AS THEY PROBABLY HAVE PARTS IN STOCK.

Ebay sells a replacement handle that looks exactly like factory handle but just screws on, it is a very common thing to break, as mine did.
