Where does the fuse go for the secondary information center on a 2002 Yukon Denali XL

SOURCE: 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.

SOURCE: 2004 yukon xl denali self-leveling rear air shocks

There's a lever that connects the driver-side rear shock to the Automatic Level Control module (the air compressor and the ride-height sensor). Disconnect the lever from the shock and rotate it up and hold it. The compressor should kick in when you hold in place after a few seconds. If it doesn't kick in, make sure your fuses and relays are good. Otherwise, you may have a failed ALC module/burned out air compressor (from the shocks being shot). After you replace the shocks (and after you recouped from the heart attack you had when you shelled out $500+ for each shock), replace the ALC module/compressor (it's all one unit), and test it - it should kick on when you rotate the lever up again.

Figure about $350 for the ALC module from your dealer, and make sure the part numbers match! Your truck came with an upgraded ALC module from the 2001-2004 module, which were prone to water damage.

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.
