2003 GMC Yukon XL with a check engine light on. ... HOW TORESET CHECK ENGINE LIGHT, FREE EASY ...

I'll try to help, everytime something gets replaced on these yukons, that circuit needs to be RESET ! Is there a reset button, on your steering wheel, to reset a variety of functions ? , check owners manual, or call your dealer for better advise

{: ) It's either you shoud have the Radio VIN releaarned by a scan tool, or you may need to reprogram the radio using GM's SPS programming.

What size engine ? 4.3 L vortex P0300 random misfire code is usually associated with vacuum leaks , but could also be low fuel pressure , plugged fuel filter , fuel pump problem , clogged injectors etc... doing fuel pressure an flow testing would confirm or eliminate that as a problem . Fuel injector balance testing would confirm or eliminate clogged injectors .

How to fix the steering wheel options on my steering wheel, for instance the volume for radio, onstar, etc? I have a '03 gmc Yukon denali xl

the check engine light means you have a trouble code in your vehicles computer. After fixing the problem with the yukon the check engine light can be reset sometimes by disconnecting the battery and disconnecting the ECM fuse. Although some parts stores are known to check your codes for free they might also clear them with a scan tool.

take it back to dealers ands ask nicely before get the baseball bat out

you have to take it to a auto part store and they can tell you if there are any problems using a key code and then reset it

way different vehicle then i own but when i blew the fuse on the factory amp i had no sound.... have a look at your fuse panel.
