Check the main fuse box under the hood on the drivers side. You should do it with an ohmmeter. good luck. The cruise control is probably the door lock module. Are your interior lights stuck on?

1986 dodge 3/4 four wheel no brake lights have turn signals running lights power to the switch and new bulbs


Turn signal and brake lights operate from a different switch. The brake light switch is under the dash behind the brake pedal. Look under the dash and follow the brake pedal up until you see a switch which the pedal operates. Normally a white plastic switch with two wires. Disconnect the two wires and touch them together. If brake lights come on replace the switch. If not use a 12 volt test light to see if there is current to one of the wires. If not, check for a blown fuse. This should solve your problem. If not, contact me for further information,

Abs brake light coming on.


Your Antilock Brake System (ABS) has a problem. The ABS will not work at all as long as the light is on. A common problem is a bad Front Wheel Speed Sensor. This system also uses the signal from the Vehicle Speed Sensor that is mounted in either the differential or the transfer case, depending on if you have 4 wheel drive. There are many other things that can cause this light to come on, but these are the most common. You will need to have your Electronic Brake Control Module (EBCM) scanned to find out why it has turned the light on.

My Advtrack, ABS and AWD all get Disableed


The sound could be isolated and may not be related to you not having 4wheel drive. You may have to inspect the speed sensors on the hubs of the wheels. You may have it inpsected and see if there could be a faulty sensor. Some 4x4 relies on sensors for 4x4 to work and these sensors also help ABS to work. Inspect the drive shafts as well. This may have caused the noise and may have affected your 4wheel drive capabilities.
