Do you have to remove the seat to replace the female end of the seat belt on a 99 park avenue?

clean it or replace it.

Replacing a front turn signal bulb is easy, as I just did my own. On the front driver's side, look at the wheel well splash panel and you'll see one plastic pin. Use a claw hammer and pull the pin out. Now just pull the plastic splash panel out of your way.

Look behind the front bumper and you'll see the light fixture. The top left wire and & bulb socket is right there. Give the socket a 1/4 turn to the left and you have access to replacing the bulb which is a 194, available at any parts store, 2 for $5.00.

The most common problem is the gear breaking under the seat. There is one motor to make the front go up and down and one motor to make the back go up and down. The front up/down motor is the easier one to replace. I have a video of one way to fix the up/down motors. I demo the back motor. Here is the link to my video: http://www.youtube.com/watch?v=wQLVvUf-9rs

The fuse for the sunroof is located under the back seat. The back seat can be removed by pulling up on the front (slide your fingers under the front side of the seat and pull up.) There will be a 3" square black box just about the middle of the seat area. This fuse box should have a 20 amp mini fuse (yellow in color) for the sunroof next to a line of 3 other fuses (15 amps and 10 amp fuses if I remember correctly.) Mine was not burnt out, so it's on to the next step of checking the wiring from switch to motor... :)

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

have a look to see if its coiled in twisted as you pull the belt out if the buckle doesn't line straight to the female end well its probely retracted in twisted to repair pull the belt out all the way and then realign the belt its quite hard to do so take your time hope this helps.

replace the motor

Take off cover and check it out. Worst case New Seat Belt Assy and you will need the special torx type driver socket just for seat belts to remove it

Firt - study & write down (draw) the belt path,,
and be sure about it..

Then - put a wrench on the nut in the center of the tension pully.. Move the tension pully to loosen the belt.. Pull belt off..

Repeat to put new one on..

Should be pretty easy..

its behind the glove box i just replaced it myself and im a girl!! you go girl!!!
