When i turn on the wipers and the radio they work fine ,when i turn the light switch to road position and hit the dimmer switch the radio and wipers stop working.The blower motor work fine at any position. I tested the lightswitch and the dimmer switch ok. checked for power at the dimmer switch i get 5 -7volts at the orange wire #113,. I am wondering if the circuit board is the problem.

STOP and PARK LPS will be tail lights.

ILLUM and GAUGES will.be dash lights.



STOP
Stop/CHMSL, Stoplamps

GAUGES
IP Cluster, DRL Relay, DRL Module, HDLP Switch, Keyless Entry Illumination, Low Coolant Module, CHIME Module, DRAB Module

PARK LPS
License Plate Lamp, Parking Lamps, Taillamps, Front Sidemarkers, Glove Box Ashtray

ILLUM
LP Cluster, HVAC Controls, RR HVAC Controls, IP Switches, Radio Illumination, Door Switch Illumination

Alas, a problem for the shop. A bad wiring harness might be involved. But I would be overcome with the urge to check the fuses.

2005 Malibu NO POWER except Security Light on Dash

2004-12 Chevrolet Malibus have been recalled to modify the brake lamp wiring harness

Did you check the dimmer switch for the dash lights ?

Defective switch or wiring between switch and motor. The 1 wire that does have voltage is for the park function. I would pull the switch and test for voltages going into the switch, with ignition switch on, then turn the wiper switch on and see if you have any voltages coming out.

ignition switch needs replacement

you could have a short in the ignition itself, which as the keys swing back and forth causes a stoppage in the circuit, Mercury has had that problem for years , check all fuses, and with the wipers check the relay also, as far as the lighter,, they will short out , and most car makers suggest not using them for added purposes since they tend to go bad , they were intended to heat a small wire that draws low amperage,, enough to light a cig , some plug in units require more amps and will heat up the socket , which will then short out, causing damage

u changed the multifunction switch or the main head light switch?

Should be a 40amp fuse,

Are these interior lights our the headlights? If it is the interior lights, you should pull the dimmer switch and check for a bad connection especially the ground connection on the back side. If that is okay, you may need to buy a new switch. If it is the headlights, check for a bad relay.

possibly the dimmer switch on the floor? happened on my 91 half ton dims didnt work but brights did and then they cut out altogether. a little water goes a long way
