Various lights on dashboard are flashing. Help please?

you can get the trouble codes out by turning key on off on off on then watch the check engine light it will flash a number of times n pause this will give you codes to take to the auto parts store n tell them they will know most of them the service writer at the dealer can find the rest (example) blink blink blink pause blink blink =32 there could be several so do it a couple times to make sure you get them right and get them all

I've got the same issue on my 02 Explorer. I've replaced the alternator and light switch. Still have the same issue.

no clicking as if alternator were bad ?? No clicking would be the starter solenoid , not the alternator ! Your best bet would be to take your vehicle to a qualified repair shop . Unless you know how to do automotive electrical testing ! How to use an read a wiring diagram ? We use wiring diagrams to see what all is involved in a system , circuit etc..... An we take training classes !

How to voltage drop test starter motor circuit

There are many different sources for the light to come on. Anything that caused combustion to fail, commonly called a misfire will set the light. Various sensors such as oxygen sensors that evaluate the exhaust before and after the gases are burned in the converter. Transmission codes may set the check engine light to appear. If the car is running okay, get it fixed in a reasonable amount of time such as within the month. It will probably save you fuel if you do. However if the Check engine light is flashing, you should not be driving it as damage is being done to the converter.

Depending on which light is flashing will determine whats wrong, normally thee are three lights that flash one is yellow check engine light, when it flashes it means a misfire and catastrophic catalytic converter failure. Red oil light means your low on oil and if it does not have a gage you may have damaged the engine and then there is several others like air bag warning light this would be caused by a defective clock spring, or a malfunction in the computer system. Your best bet is call your local dealer and describe to them your problem and tell them what lights are flashing they can determine weather you should drive it or have it towed in for repairs. Remember FLASHING RED OR Yellow light means imminent failure of expensive engine parts.

Most likely it is the ignition switch (the key ignition switch) in the steering column ($100 at a dealer).

It may be a loose negative battery ground cable, too.
Check the negative battery cable where it conencts to the engine ground. It may be loose, corroded, damaged, or otherwise not making a good ground contact.

Add a grounding strap ($11 - AutoZone) from the engine to the chassis. That may help, but it's most likely the ignition switch.

check air filter and spark plug wires

ELECTRONIC STABILITY PROGRAM ( ESP) LIGHT FLASHES TO INDICATE UNSTABLE DRIVING CONDITIONS....WHICH WILL ALSO COME ON IF YOUR ENGINE IS MISFIRES.. CHECK THE COILS AND SPARK PLUGS FIRST THEN GO FOR FUEL..INJECTORS...FUEL FILTER CHOKED..HOPE I WAS OF SOME HELP TO YOU..

Could be a bad light switch or relay, but I'd check dash and body grounding first. On every Jeep I've ever owned, I run a direct ground to everything before I even drive it. To do this, Attach a 12ga or larger wire to the battery ground connector. Run that wire around the firewall side of the engine bay, removing insulation at several points and attaching the exposed wire to the firewall, (using short, self-tapping screws) both fenders and ground points for the computer. I also attach one additional leg which runs through the firewall (careful not to drill through anything important) and attaches to the metal frame of the dashboard. I also add a second ground wire directly to the engine block, eliminating any possibility of a poor ground anywhere. It sounds like a big job but it's not, and doing this precludes many frustrating and unnecessary problems down the road!
