I have a 1999 volvo c70 coupe that do not have power seats fitted. when i pull the side lever up to tilt the seat forward nothing happens. both front seats wont tilt so passengers can get in or out. many thanks podge.....

heck for 2 bolts at the lower edge near the floor if no bolts push lower seat inwards and lift up it should pop up , use a large screwdriver.

best thing to do is replace both front calipers and brake hoses attached to the calipers.you can get rebuilt calipers from a local parts store which are cheaper.

Hi, follow the instruction below......

1. Remove the lower seat cushion by pulling straight up on the front portion and disengaging the clips. Then hinge the seat upward to release the rear clips.

FUEL PUMP IN FUEL TANK.YOU DID NOT TELL ME WHAT VOLVO YOU HAVE S40 V40 C70 S80 V70 V70XC.YOU CAN ACCESS FUEL PUMP BY TILT REAR SEAT FORWARD REMOVE.FOLD BACK TRUNK COMPARTMENT CARPET.REMOVE FUEL PUMP PROTECTIVE COVER.THIS PROCEDURES FOR VOLVOS I JUST MENTION AT THE ABOVE INFORMATION.

There is a lever on the left side by your **** that tilts the seat forward or back. There are knobs on the side that you turn to raise the seat front up or down, there is a handle under the front of the seat that you either pull up or pull to the left to slide the seat front or back. And depending on the seat there might be a lever on the left side of the seat back that controls how much lumbar support.

first, you have to lift up the seat it self, and tilt it forward towards the front seat using the loop handle. (the back of the seat goes from 3:00 up to 12:00)
then pull the lever on the top of the seat-back (near the head rest) and move it from 12:00 to 9:00.

4 bolts is fairly easy remove the rear first with the seat all the way forwards and then put seat all the way back then 2 in the front remove them ..tilt the seat back and if there is any wire harness disconnect them as well ...reverse process for re-installation

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.

The same thing happened to my 99 C70. I had to replace coils, in the engine...has somewhat to do with the spark plug stuff. Cost me $600.
Also the electric seats go out, they are lame. I spent $150 fixing my driver side one time, then it went out again...and is stuck...but okay enough for me to drive, and I refuse to fix it again.

you will need to check to make sure no coins fell into the track and is jammed it if not you will need to replace the bottom frame of the seat possible with a junk yard one much cheaper than buying new and junkyard frames come complete.
