What Owners Say
"Left turn signal would intermittently fail to function. Sometimes it would cause the emergency flashers to activate. It cost me $118 to get the problem diagnosed and an additional $425 to have the "combo switch" black box replaced at an independent garage. I sure miss the days when I could pick up a turn signal flasher switch for $2.50 at my local auto parts store and replace it myself in under 5 minutes. Such is progress"
D M., CA (2005 GMC Sierra 1500 Base 4.8-L V8)"Running lights on the front of the truck will not stay working. It seems to be something in the system that blows the bulbs out. I fix one and the other side goes out and fix that one and within 30 to 90 days the other goes out. I follow all proper protocol on installing them with the dielectric grease to no avail the still burn out. Even using different manufactures bulbs to see if that might be the problem but it hasn't been the case. Maybe not as often as I have stated but I have purchased over a dozen bulbs since the purchase of this truck and have had to replace NONE of the tail lights, I find that odd to say the least."

Anonymous, ME (2005 GMC Sierra 1500 4.8-L V8)"The instrument cluster in my truck recently began to self destruct. The speedometer began to get very notchy and got worse until it quit working. One by one the other gauges in the cluster have stopped working. I found out that GMC had recalled the instrument cluster but never got notified of the recall. I bought the truck new so they knew who owned it and where i lived. The recall has since expired and i’m Stuck with a repair although not as expensive as the AC compressor i replaced in this truck, still aggravating at . $270 for a reconditioned unit on EBay."
Terry L., MO (2005 GMC Sierra 1500 SLE 5.3-L V8)"The instrument panel developed a problem which caused the analog coolant temperature, oil pressure, battery voltage, and fuel gauges to become nonfunctional. The entire instrument cluster had to be replaced which cost me around $800. The service writer claimed that it was due to a design or production flaw that GM was refusing to pay for. Come on GM! you've been making analog gauges since the 1920's and should be able to get them right by now!"
D M., CA (2005 GMC Sierra 1500 Base 4.8-L V8)"Can't see the gear selector lights, gas gauge and other dash lights that are going bad. No longer can you replace the bulbs in the dash board you must replace the whole dash cluster. Makes for a simple build but repair becomes more expensive by a HUGE margin."

Harry F., KS (2005 GMC Sierra 1500 SLT 5.3-L V8)"Not much to tell. The heating element shorted out and would auto shut off.It would have been a major expense at a dealership but repaired for under $500. It all started occasionally shutting off but by the end it would shut off immediately."
Anonymous, CA (2005 GMC Sierra 1500 SLT 5.3-L V8)"The lights illuminating the controls on the doors, steering wheel and dash are almost all burned out now.
