Gmc envoy wont restart gauges dont work

Unread post by Jodie » Thu May 11, 2017 2:53 pm

I have a 2003 gmc envoy. This morning it started fine but once I turned it off it would not start. The light come on. My radio and gauges dont work. I have checked the battery and the contections. Sometimes my security light stays on and sometimes it goes off. Any ideas?

make sure you have power to the ignition switch from the "IGN A" fuse 34 (40a) in the underhood fuse box. If you do have power going through that fuse you should check your ignition switch. Make sure you have the correct power going in on the red wire and going out on the white wire ACC, RUN and START and out on the orange wire in RUN and the yellow wire in START.

so your 06 envoy starts and runs okay but you don't have any dash lights or gauges working?

you could check the fuses for power. In the under hood fuse box, fuse #24 the IPC/DIC 10A fuse and the IGN E fuse #22 a 10A fuse both power up the dash cluster.

A good scanner can hook up to your car and look for the data stream for the instrument cluster. It should have it's own module and the scanner can see if there are any codes or if it can communicate with it. See if it's getting power from the ignition switch.
