it has to do with your air ride suspension best bet is take it to the dealer there is probably a problem with a level sensor. hope this helps you

SOURCE: Collision System Sensor in 05 Yukon Denali xl is malfunctioning

you have two front collision sensors int he front. drivers and passengers. if you know which side it is then just order one from the dealer. to replace the sensor just disconnect the battery and locate the sensor, they are mounted below the rad. unbolt the bad sensor unplug connector and mount new one.. plug in connector and then reconnect battery. the airbag light will come on for the startup procedure and then once the airbag startup is passed and no problems are found the light should go out. Good luck

You can get the codes checked and see if you have a level sensor code.The level sensors are known to go bad on these vehicles.Sometimes when you rock the vehicle it will start to work properly.What happens is the fingers on the level sensor wear out and it works erratically.You can get the level sensor separately from the fuel sending unit.Hope this helps.Good luck.

Does it work on any speeds? If it still works on high then the blower resistor is bad. On the passenger side under the glovebox is the blower motor and resistor.If possible try wiggling the pigtail plugs that attach to these two components.It is not uncommon to have problems with these pigtails.Also try tapping the bottom of the blower motor to see if it will start working again.If it does The connections are poor and need repaired. If the blower will not work at all check for power at the blower motor pigtail with a test light or dvm. Will be glad to assist further if more assistance is needed.

I had an 2001 or 2003 envoy that did that and the only solution was to disconnect the battery for about 5 minutes so the computer would reset.

Location of fuse box/panel for 2004 yukon denali xl


There are 2 fuse panels in the Denali.
One is a panel on the drivers side, its on the dash but facing the door.

The ohter is under the dash and above the pedals, this one is much tougher to access.

Your Owner's Manual should tell you where the fuses are that you need to access.
