    that light comes on with a timer...it is programed to come on at a certain time and means that you need to change the O2 sensor...the only way to turn it off is to have the dealer reset it with a special machine, and re-set the timer....OR do like I did....remove the bulb, it is only a reminder to change the O2 sensor, it doesn't mean anything is wrong, so removing the bulb doesn't hurt anything.

If it didn't come with fog lights, it may also have not included a fog light relay and/or fuse. Check the owner's manual for fuse and relay locations, and then check if the necessary parts are there.

Check engine light went on while driving. The car was warm and had been going for at least 15 miles. It is an 8 cylinder 1997 Jeep Laredo with 166,750 miles


The check engine light will come on when the computer detects a problem. You need to get the code(s) retirieved, they will tell you what the problem is and then you can figure out how to fix it. Any OBD II code reader will do the job, and some auto parts stores will do it for you. Since there are a number of things that can cause the light to come on, It would be too hard to guess here.

Perform service light on what does it mean?


If it is only "perform service", this is likely your mileage counter telling you to get an oil change. If it was a "check engine light" it would be amber in color and would require use of a scanner to acquire codes and check for faults. Here's how to reset:
On a 1997 Jeep Grand Cherokee Laredo if the "Perform Service" light is in the middle of the dash Simply press the "SET" button until the display shows the "0 miles to service", Then hold the other button below it down until it resets to "3000".

What does perform service message mean?


This is a oil change reminder. Nothing fancy about, when you get your oil change go into the menu and click reset counter and it will go off. If there was something wrong with your car the check engine light would come on.

Main reop light in dash


Hello, and welcome to FixYa.

The 'Maint Reqd' light indicates that you are due for an oil change. It will blink 4,500 miles since the light was reset at your last oil change, and stay on steady after 5,000 miles.

If you recently had an oil change, all you need to do is reset your maintenance reqd lamp. The procedure is here on this site inthe 'tips and tricks' section, and it is also in your owner's manual.

Engine light comes on 2003 Jeep grand cherokee laredo


Check the Fuel Pump Relay, it may be malfunctioning and need replaced. Also, in some vechicles, if the batter is disconnected and reconnected, the service engine light will come on from time to time, going off and on simultaneously. Have a diagnostics done to see if any codes show up. If no codes appear, then have them all cleared and drive for another 200 miles. Sometimes the computer will need to be cleared a couple times before the light will stay off. Make sure that all fuses and relays are good, and securey in place. Check all factory installed lights to make sure they are good, and securly in place as well.

4wh not working 91 jeep cherokee


There is a switch on top of the t-case that turns the light on when in 4wd. If the switch is bad, the jeep can be in 4wd and not show the light. Put the car in 4wd and make sharp circle turn, you can tell if the jeep is in 4wd.
