Checked fuses and everything

Hi, how do I resolve an error code B0004 for a 2003 Buick LeSabre? It's a 3.8L engine. Thanks!

can't use door without alam staying on .

I was in a accident and my A frame is shot

Bulbs and Fuse are good

Replaced all gaskets. injectors swapped and new coils only thing I think of is crack in head I didn't see and once warmed up expands causing miss fire is that possible it's only in cylinder 1 so I kinda ruled out cranks sensor any thought would be great car gas sat for bout 2 years I do start jet run it was my dads car after he passed I kept it I like to fix and use as a driver

tried everything, putting the car in N, jump starting, would not start. Went back a little later and it started. Had to push on the gear linkage, gear stick to get it to start so times. Not always.

stopped working one day, cant see fuse that links to it, had someone try replace cluster board, still not work

I have drove my car gotten in it put it in gear and it stalls 4 times now, after letting set 3 of the times it started back up . i pulled out of garage to go to work put into drive went 5 ft it died and will not turn over . car has 39,000 miles on it . I try to start it i get messages on dash , service power steering, service charging system, blind zone alert, service afl lamp, rear turn signal , and left tire shows 19 lbs . tire has 35 lbs in tire . when i push button to turn off ignition , the tack light go off and speedometer light go off, but radio stays lit, transmission gears stay light white no mark to identify what gear its in . and me accent lights on dash and doors stay on . I am thinking security module might be sending no password to BMC. Any help on issue.

Hi, how do I resolve an error code B3857 in a 2004 Buick Rendezvous (3.6L engine)? Thanks!

thermostate located in the engine

The car has remote start so there is a brake in the wires that come from switch on the hood latch. It gives me hood open all the time therefor I can never put the alarm on. I have replaced the hood latch assy to no avail. I need to know where the 3 wires go so I can replace them. A wirering diagram would be helpful.

What would cause the transmission on the Buick 2002 Park Avenue to start making a thud noise when it shifts gears? My car has just started doing that since the transmission fluid was replaced a little over a month ago. The problem is not apparent when the car is cold. But after it warms up, it becomes very apparent.

Change motor from 95 3800 to a 96 body motor were running before I change it.96 body had been sitting for a while could old gas be my problem spray stater fluid keeps running.

car won't start no gas flow

The needle goes all the way aroung and stopes at the left peg.

Had actuators checked. Mechanic said they all were working. That I must had something blocking the passenger side "Actuator". Because there is no heat going to the passenger side. Automatic dual climate control. Should I replace the actuator?

What could be the problem the rest of them work

Went to drive off and my back left tire won't move like its locked up

Needs to be replaced but not sure where to look. In the fuel tank?

There is a light of a car n paddle lock on it light on n battery light stays on for couple minutes after a jump start n dies out?

no air comes out on defrost, has duel heat, has the auto button. I have good heat , the blower works fine.

My check engine light will come on after idling for 10 minutes sometimes. When this happens and I then drive my Buick tends to have less power and a quiet winding noise, when I push on the gas pedal there isn't much power, and my Rpms move up. At other times my check engine light does not come on after idling. Sometimes when it's been on in the morning and the vehicle has been shut off for a few hours the light will be on when I start it again, other times the light is off.

i need to replace the high pressure power steering hose and i need to know the size of it and the fittings

When you put the vehicle in reverse. The three lights in back come on and goes back out.

hood has hinges that bend easy and of course are damn hard to find?? Hinges have 2 star. screw that god slightly under the hood which is a bitch to get the right angle even with 3 guys. Put hinges on hood or put hinges on the car 1st????

I have changed the oil filter housing gasket and the oil filter sending unit.

The car was given to me. It has what I believe is a ignition button under the dash to bypass system. I think. But I wad told that the key needed to be programmed. So I'm trying, but I feel like maybe this short cut that is installed might be interfering with success. Any ideas?
