First things first...your vehicle will register fault codes for assisting in the trouble shooting of some system failures (usually emissions related faults.) This system is called OBDII.

Auto zone used to provide free reading of your vehicles on board computers in the hopes that you will purchase the required repair parts there.

When you retrieve the codes either by the assistance of a parts store or by purchasing a ODBII Code reader you will have a place to start your investigation.

PS: Your owner manual may also help to identify the meaning of tell tale lamps on your dash cluster.

SOURCE: 2005 equinox, headlights won't turn on, brigts work okay.

I had the same light issue a few weeks ago. There is just a single light bulb with dual filaments for the high and low beams. All you need to do is replace the light bulb. The instructions are in the owners manual.

SOURCE: I think I have a blown fuse on my 2004 Suburban

At the back of the outer seat adjuster rail is a connector. Sometimes the conn comes apart or wires break or wires get shorted and trip the seat circuit breaker or fuse. This will happen on either side of seat. Also make sure nothing was stashed under the seat to cause wires getting caught & pulled out.

SOURCE: 2005 Chevy astro van, 4.3L A/c, Blower motor,

It could be a bad blower motor - tap on the blower motor with the end of a hammer when you have the switch in the on position - if it comes on then it is a bad blower motor. If it doesn't come on I would check to make sure you are getting power and ground to the HVAC control head.

SOURCE: 2003 Impala Brake lights dont work

The brake lights are routed through the signal light switch.
Looks like that will be the next switch to replace and the problem.

'95 Lincoln town car. Husband was driving uphill and the digital dash suddenly went dark. Radio is working and a/c is not. Exterior light still working and so are interior lights besides the dash


Could be a bad wire possibly chaffing or grounding out to to another wire or frame. Check your fuses. You may want to pull the dash out and check that wiring as well

Added freon to ac and car will not cool


Needs to be checked for a freon leak, best way to do this is to recharge and add dye, with a uv light you will be able to fine the leak, most auto parts sell the dye, and the flash light you will need to fine the leak, good luck.

Interior lights will not turn off


My guess is, the dome light has a three position switch that got turned to "always on" when you yawned and stretched. Either that or the panel switch is turned to "always on." My roommate once had this problem and for weeks he disconnected the battery every time he parked. But when I drove one time, I noticed the panel light switch was turned on. Problem solved.

Gauge cluster lights


You should have a dimmer switch that increases or decreases the amount of light that the dash produces. This should be located to the right of the steering wheel. It is a wheel that goes up or down. I believe on your model you can slide the switch all the way up, and you will feel a click, and that should be the brightest setting.

Let me know what you find out!
