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.

the relay is built into the speed resistor or motor control module ) depends if you have automative or manual heater controls. is automatic it will be motor control module and manual is the resistor module. these units are located beside the heate fan motor. the motor helps keeps the unit cool. just unbolt the module, unplug it and install new one. Just check to make sure the connector is good.. The heat created by the connection sometimes melts the power or ground leads (red or black) and if this is so you will need to replace the pin.

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
