I have a lighting bolt icon on my dashboard

ANSWER : Hello, thank you for writing in. The vehicle does utilize a lot of the same sensors for these systems. Are there any other codes that are coming up when this code appears? If so you will want to take these into consideration when processing the repair and making a diagnosis. The module may be bad, and replacing it should fix the problem. The lights should turn off once the main computer recognizes the new module and the sensors sync up. If you believe the sensors need to be cleaned you may do so. Do as minimal as possible to make sure you are not damaging the sensor or disrupting the wiring inside. A bad connection would make the lights stay on. With so many lights that are effected by the module being illuminated, the module is likely bad or does not have a connection. Check the connection first and then resort to replacing the unit.

ANSWER : Hi there. In many cases, when you have electrical problems like you’re describing, it’s caused by multiple electrical component failure. It’s likely that a few electrical relays are not working; especially if you have systems that utilize the same components (such as your brake light and tail lights). I would recommend having a professional mobile mechanic come to your location to complete an electrical problems inspection first, so they can pinpoint what is damaged and recommend the right repairs.

ANSWER : Hello. We’ll be happy to help you. There are a few things that I recommend checking to discover why your lighting system is malfunctioning. The headlight dimmer switch should be checked. Along with the wiring harness above the right front tire behind the fender well cover. Also
the main fuse under the hood should be inspected because other people with your particular vehicle have had similar lighting issues if that fuse goes bad. It will be a great idea to check the rest of the fuses in that area too while checking the main fuse. Once the fuses are checked inside of the main fuse box then I would check the fuses inside of their interior fuse box. The interior fuse box should be located on the driver side of the dashboard near where your legs would be.

ANSWER : Hello there, thank you for asking about your 1988 Oldsmobile Toronado. This is something that would require first hand inspection for complete diagnosis. However, there is a technical service bulletin (TSB) that may pertain to your issue. The TSB is number 89-T-129 and it deals with an "Electrical Problem" message on the message display and erratic air conditioning operation. The solution is to replace the HVAC control module with an upgraded one. There is also another TSB 89-T-140 which deals with intermittent climate control and instrument cluster operation due to a faulty solder joint in central power supply. The fix is to replace the unit with an upgraded model. I recommend having the pros at YourMechanic diagnose the electrical issues and repair this problem for you.

ANSWER : Your car has what is called a "safe mode" that will be engaged by the computer when it detects that something critical has gone wrong related to any of the major components in your engine chassis or power train. This may be related to a number of things, most of which should have been registered in the computer when the check engine light came on. I recommend having an expert from YourMechanic come to your location to inspect your check engine light and diagnose any codes registered by your vehicle’s computer.

ANSWER : Hello there, thank you for asking about your 1993 Isuzu Pickup. It sounds like a bad ground in the instrument panel circuit. Looking at the wiring diagram, I see the AC heater control panel and instrument cluster share the same ground, which is designated G200. That is the first place I would start. Electrical diagnosis and repair can be tricky, so I suggest you have a professional look into this for you. A certified technician from YourMechanic can inspect your car’s electrical problems and make the necessary repairs.

ANSWER : It could be that the dash and taillights share a common fuse. This could be determined by looking at the fuse information in your owner’s manual. One important thing to remember is that fuses don’t blow for no reason – they blow as a result of too much current being drawn. So, if you do find a blown fuse, you’ll need to track down the reason it blew in the first place. Other potential causes for your problem include a short somewhere in the circuit or a faulty light switch. I suggest you have your vehicle inspected and repaired by a certified technician, like one from YourMechanic.

ANSWER : This is likely a brake light switch problem. I would suggest testing the brake light switch which should be located down by the brake pedal. This may also be a computer problem as well as indicated by the other lights on in the dash. I would recommend having an expert from YourMechanic come to your home to possibly replace the brake light switch and diagnose with a scanning tool which will download useful data from the truck’s computer indicating what specifically the problem may be.
