Hi, I have the GT model and I have following electrical problem: Everything seems to be working except fuel and coolant temperature gauges, dashboard light, clock, radio, passenger room light, remote lock/unlock and the door light. I checked all fuses and they seem to be okay so I assume it is one of the relays. I do not have the wiring diagram and I am not able to get it from www.hmaservice.com, the site is not cooperating properly with any of my computers (regardless of SVG plugins). Could you please either send me the wiring diagram or (better:-) give me an advice which relay (if this is a relay issue) it might be, please? Thank you.

I believe you have more than one fault resulting in all the components not working.

For the gauges, check fuse # 2. Use a DVOM or test lamp to check the fuse. Swap fuse with others of similar ratings to test.

For radio check fuse # 9, underhood fuse box. Door and room lights are related to radio, check fuse # 25.

I have most of the same problems. But I have head lights, dash lights no power to obd2 port, door chimes, odometer resets. I replaced the ignition switch, ECM, checked all fuses. Replaced condenser, 1 and 2 relays. Alternator reads 14.3 volts. Is there a fuse-able link somewhere that I am missing?

It sounds like the ignition switch has failed but to confirm the issue lets test for power coming out of it. Here is a guide and the wiring diagrams to help confirm the issue:

Please run down these guides and diagrams and report back.

Thanks for the tip. The first thing I did was put a new OEM ignition switch in. Added new grounds from engine block to the body and from the battery to the body also the ECM (thought that was the cause of my rough idle in gear). I am thinking it is in the junction block under the dash near the kick panel page #2 of 7 which also goes to the courtesy light system.

Okay, here is a guide and the wiring diagrams for ou to check for power and ground for the cluster this will give us an idea of what's going on. Check for power at the fuses.

Not all fuses have power but all test good, all fusible links test good, no power to the memory circuits. I do have the Mitchell 1 subscription for all my vehicles so after studying every system wiring diagram I think I have traced it to the body computer. I am going to stop at the dealer with my VIN number to find out if it is with or with out ETACM then take a trip to the junk yard.
