SOURCE: Best way to remove rear 3 spark plugs 2000 buick

Most GM fwd v6s' have to be rolled forward to change the rear plugs. Its not as hard as it sounds though. Usually removing the air cleaner box and then taking the bolts out of the two top wish bone mounts allows you to roll the engine forward enough to change those plugs. You'll just need something to hold the engine forward while you change them. Like maybe a friend or a strap. I hope this helps you.

No spark on one igniton coil of 2000 Lesabre buick

Hi Glen, If the problem persists after replacing the coil I believe you must look at the cables for an internal broken circuit. Also check the ground connection. If all else fails check the computer. Regards John

How do I fix the drivers side front seat heater on a 2000 Buick Lesabre LTD? It appears to be the heating unit and not the switch.

Hello: It would be best to replace it, We fixed (per GM Instructions) but they didn't stay fixed so that's why I recommend replacing it. To replace it you have to remove the outer cover on the seat cushion. Bottom.
