2004 GMC Yukon XL Denali Problems
One or more heater & AC (HVAC) temperature and/or air delivery mode door actuator may fail, resulting in improper temperature or air delivery. If this occurs, fault code(s) should be stored in the HVAC control module which should assist in diagnoses.
The rear window defogger may stop working due to a wire terminal broken off of the rear glass. Our technicians tell us that terminal can be reattached using a special glue or silver solder.
It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.
2004 GMC Yukon XL Denali Questions

I just bought a 2004 GMC Yukon Denali XL used with 91k miles on it. Just started having an issue when I go to turn it on. I put my foot on the brake, turn the key, dashboard lights up and the engine makes some noise but it doesn't turn on. Do it a second time and it turns over.
The thermostat was replaced because the heater was blowing cool air when sitting idle but would blow out warm/hot air once the truck was in constant motion.
2004 GMC Yukon XL Denali Recalls
The retainer clip for the fuel rail pulse damper may fracture and allow the damper to come loose from the fuel rail. A fuel leak in the presence of an ignition source may result in a fire. Dealers will replace the engine fuel rail pulse damper free of charge. The recall began August 31, 2006. The GM recall number is 06080.
On vehicles equipped with the Bosch hydraulic brake booster, the boost pressure accumulator may crack and break away from the hydro-boost assembly during normal operation. If this were to happen while the hood is open, fragments from the accumulator could injure people standing in the immediate area. The loss of fluid while driving would cause increased steering and braking effort and a crash could occur without warning. Dealers will test the hydro-boost assembly for function of the two-function valve. If the hydro-boost assembly fails the test, it will be replaced free of charge. The recall began March 23, 2005. The GM recall number is 05006.
The hydro-boost housing relief valve bore may be out of specification. The seal may fracture as a result, which may reduce braking assist and slightly increase the steering effort while braking. Under certain conditions, more braking effort will be required to stop the vehicle. Dealers will replace the hydro-boost relief valve. The recall began June 18, 2004. The GM recall number is 04004.

2004 model. Had recall repair for hazard light activation instead of turn signals in use. Occasional hot air from passenger side dash vents instead of cold when AC in use. Service ride control message came on last year. Water pump failure this year causing engine light and hot coolant message. Other than that, four accidents cause by others and this SUV has protected me and my family fabulo...
Bought this new and have had no problems until last week. At 75,000 miles the front brakes were completely shot on the inside and almost new on the outside. The front left wheel bearing also went out. Other than that, have done nothing but basic maintenance.
