How do you remove the door panel on a 2000 Buick?

Remove the bezel around the door handle (pops out) disconnect power lock connector

Remove the power window switch (pry up towards front then slide towards front) disconnect connector

Remove reflector (pops out) remove 7mm nut

Stick fingers between door and panel and pop the push pins out, do not go go crazy here as you will break the door panel handle retainers.

Lift up on the panel, you will see a metal bracket that slides into two black plastic retainers if you are looking through the power window switch hole.

Disconnect speaker wires

Once panel is off, push in on the metal spring clips holding the black plastic boxes and slide off, re-attach to metal bracket on door panel(makes install easier) Install is reverse Hope this helps

I bought a used 2000 Buick LaSabre and almost immediately dropped another $400+ for a driver's side window regulator (installed). I contacted the original owner who stated he had to replace the rider's side regulator at the dealer's service dept for over $500. I did some after the fact investigation on the net and found that there are many Buick owners having the same problem with window regulators. I've got my old regulator with a good motor and will redesign the sucker to work without having to replace it every year or so, but it would be good to have the removal instructions for the door panel so I won't tear it up trying to get to the regulator. Any help or direction to info would be appreciated. Thanks

How do you know if your erg valve or erg vacuum modulator valve needs replacing?

It's almost impossible to tell just from how engine is working. Unless you have hesitation, car lacks power and efficiency is low. And of course if you have EGR error code(s). In order to test EGR you need to have a small vacuum hand pump. Then you need to apply vacuum to the EGR system and see how it responses. Also, sometime EGR valve just needs to be cleaned. For the you need to remove the valve and check on presence of carbon deposits. Also if the valve itself cannot be moved freely, it might have to be replaced.

The hoses around EGR system have to be checked on cracks, and replaced if cracks are present.

EGR vacuum switching valve usually does not break. But EGR valve get very dirty time to time and has to be cleaned or replaced.

How much horsepower does a 350 have?

1960's had about 300hp

1970-73 had about 300-330hp

1974-76 had about 250-200

1977-81 had about 200-175

1982-84 had about 200-150

all this is depending on what bolt on's you have (Headers, intake, carbrator etc..). If its a stock 350 then it has lower horsepeower because of the years. If it's rebuilt and tuned properly it'll be higher

If you have bored the engine out then it would become a 355 or 383 with a stroker kit. Which results in alot high performance.

I have a 1977 350 which only made about 175 on the dyno when I bought it. I have since then rebuilt it. I bored out .030 (355) added a new crankshaft and new camshaft and lifters from Edelbrock, aluminum heads from Dart, Long tube headers from Hooker, tunnel ram from Weiand, dual Holley 600cfm carbs, and a new oil pan from Moroso.

Added up all I am making well 569 horsepower with this set up.
