Lumina troubleshooting
Check fuse.
Check if center light works.
Check for power at light sockets.
Check brake light switch.
Manipulate the turn signal lever.
- To check the brake light fuse, open the passenger door and remove the fuse panel cover that is located around the corner from the glove compartment. On the back side of the fuse panel cover there should be a fuse location chart. The brake light fuse is #23, located in the socket that is dead-center among the mini fuses. I believe it is supposed to be a 15A fuse. Confirm the condition of the brake light fuse and replace if necessary. If the fuse fails again, determine and correct the cause.
- Also, see if the center brake light is working properly. If it is, then the brake light switch is working. If the center light is not working, the brake light switch is suspect. That switch is a spring-loaded plunger switch that is of the "normally closed" variety. In this application the switch is usually held open by the brake pedal arm, except when he pedal is depressed. Then the spring within the switch holds the contacts closed so that the brake lights will operate.
That switch is located under the instrument panel. Look for a push-button switch that is contacting the brake pedal lever. If the car has cruise control there will be two switches, one above the other. I believe that the lower of the two is the brake light switch.
- With the brake pedal depressed, see if you have power and ground at the brake light sockets. One good way to confirm that is to remove a brake light bulb and connect a 12v. test light across the contacts in the socket.
- An operating center brake light combined with no power to the 12v+ terminals at the left and right brake light sockets could indicate a defect within the turn signal switch. If you get to the point where you suspect a defect there, try applying rearward pressure on the turn signal lever and see if the brake lights work then. If that procedure confirms that the defect is within the turn signal switch, you can replace the turn signal switch. Or you could try my trick which cost me less than a dollar and has worked for years.
See attached photo.
Spacer (piece of rubber tubing?) is used to apply rearward pressure on turn signal lever. I have not disassembled the switch assembly, but evidence suggests that electrical contacts inside the switch depend on the mechanism being positioned properly. If the internal positioning device failed (perhaps the lever was pushed forward) then an external device can be made to hold the lever and switches in proper location.
If you attempt this repair, consider applying some lubricant as deemed necessary.
Good luck.
Radio unlock codes
Need dealer to retrive code from computer, look in owners Manuel some customers write the code in radio section.
Problem air conditioner
Does the Air Conditioning compressor engage when the A/C is selected?
Does the blower operate properly?
Please describe the problem in more detail.
Is there a way to check if just one spark plug wire is bad?
I presume taking off the other leads makes a difference...
OK, taking the lead off stops the cylinder from firing. If this does not make a difference to the engine power SOMETHING - NOT necessarily the lead is wrong. You must do analysis to find out what is wrong. I recommend:
Check if spark comes out of lead. Run motor and hold near block to see spark jump. If not, swap lead with another and test again. Replace if not working, or if works distributor or coil may be wrong.
Check spark plug. Remove and if looks bad replace it. If OK, swap with another cylinder and see if fault follows. if it does replace plug.
then Check compression. Check petrol is getting thru.

What is a liquid line on a auto ac system?
ORIFICE TUBE AND LOCATION IN VEHICLE If you are not somewhat mechanically inclined you should let a professional do this as the AC coolant will be released. You will have to re-charge the system upon completion. Here are some quotes from on-line mechanics to give you a better idea what you are looking for. The Orifice tube can be determined as faulty when your AC doesn\'t cool properly in the summer or heat well in the winter. Often you will smell antifreeze inside your car\'s interior. "It\'s buried pretty good. It\'s in the liquid line that runs along the left inner fender well, under the brake booster. If you look closely at the line, you will see a connection and dimples in the line where the tube is located." Quote from ASE: Wrenchtech Aug 2011. The liquid line is located in the area of the abs pump. "The fixed orifice is located in the inlet tube to the evaporator core, this is where the small high pressure AC line from the compressor connects to the tube sticking out of the engine firewall, u will most likely need a special tool to remove it," below is an example of the tool, "don\'t damage the evaporator core by trying to remove the orifice tube without this if it is stuck down in the tube." ---Dennis Weid The tool comes as a single apparatus or you can get the kit. Here are some examples of manufacturers who make these parts. I have removed the sales information because there are literally hundreds of choices out there including your local parts stores: Mastercool 92311 Deluxe Orifice Tube Repair Kit This 5 piece universal kit will remove and install any style orifice tube. Another suggestion comes from Ronnie Bennett Sr.: "The orifice tube will be on the small line joining the evaporator, the ac line will be swelled where the orifice tube is at, you may not see it, but use needle nose pliers to remove it, and to install it." But I would look at YouTube for a better understanding of what you are looking for, how it works and how to remove and replace it, so try this site to start with and look further. You\'ll be surprised the amount of data available and a video is worth a zillion words. https://www.youtube.com/watch?v=ae3zQQOhkDY Dennis If you haven\'t seen pictures of the part, this is what it looks like:
