Then inside the car, You must remove the lower dash plastic shield held on by 10 screws and then 5 screws holding the base of the glove box. Let the glove box drop down out of the way. Look at the upper back foot wall for a SILVER METAL BOX with (3) big wire plugs. The plugs are (RED - WHITE & BLUE) that's the computer unit. It's mounted on a thick hard plastic back board. Use a Blade screw driver to push on the corners of the back board as you push up to release the snaps of the computer. Do this to both corner snaps. Once you have done that You can pull the computer down and out to the car floor.Now use masking tape, mark each plug wires to match RED/WHITE/BLUE PLUGS!Now squiz the ends of the plugs and pull hard to remove them. NOW your old computer is OUT... Buy a New / Rebuilt or USED compoter. IT'S BEST that you Match the (DELCO NUMBER on your old one!)**** DO NOT BUY ONE AT THE DEALER!!! THEY WILL KILL YOU BANK ACCOUNT!!!! BUY ONE AT JUNK YARD FOR UNDER $125... MAKE SURE IT IS A DELCO UNIT WITH THE SAME PART NUMBER AS YOUR OLD ONE! *** DO-NOT GIVE THE OLD UNIT TO THE JUNK YARD!!! ***ONCE You have the repacement unit, remove two screws from the top shield of the new one and your old one. Inside you will see a (BLUE) plug in chip. You need to SWAP them from your old one to the new one. Squiz and lift out and move your old one to the new computer.DO-NOT Put it back in the dash yet.... After you have swaped the BLUE chip put the 2 screws back and plug in the RED, WHITE & BLUE big plugs back on the new computer. Let it lay on the car floor for now. Now, go under the hood and RECONECT the NEG to the battery.Start your car and let it run checking for problems fixed!!! If all OK, take it for a short test drive... If all is well go home and put computer back and reasemble in reverce order. GOOD LUCK!!!

These cars are well known to have and EGR valve sticking open or going bad. Remove the valve and check the pintle to see if it's stuck open, sometimes you can just clean them with carb/throttle body cleaner.

try the fuse panel in the engine compartment... it has a cover on it and is usually located near the battery.

The orifice tube is located inside the liquid line where it connects to the condenser. This line is located on the passenger side of the car and has the low side charge port on it. this line unscrews right where the orifice tube is located... Hope this helps

i would say fuel module

On my F250 when the windows went out I had to replace the drivers side switch to get both working again. I am putting my money on the switch is bad. Some of these control panels are all wired together in one so it would make sense that your seats went out as well if all controls are on the arm rest. This on the up side is not a difficult or that expensive to fix on your own.

HelloThe engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM
