FROM LUSTY KID:
Check your bulbs first, I have lost both headlights on my ford at once on account of the bulbs burning out at the same time. Same thing probably happen, you have one filament out. The lights can work, but if the filament for brake is burnt, you don't see brake lights.
As for the cruise control. Check fuse box first. If OK check vacuum hose to actuator in engine compartment for starters.

I had the same problem with my 1999 Yukon. The electric board needed to be replaced. Rust starts to build up and shorts out or blows the bulb. The dealership charged $73.60 for the part and I installed it myself (Saved $30).

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

you have to fix the problem with ur brakes- first check the wiring ,connectors and connection clips to the abs sensors and modulator if looks ok than have truck scanned some auto stores such as auto zone / advanced auto do it for free the code will give u a start point towards fixing ur problem--visual inspection of brakes doesnt always show problem

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.
