Hello All,

Purchased my 05 with a bad transmission, Replaced it myself and love it!
I found the bad CEM from water intrusion and had the great folks at Xemodex repair it.
Really starting to get the kinks worked out and now the final phase:

I have a few problems you may be able to help with.

1) No headlights. Nothing. Notta. Neither side.. Dash warning comes on; Low beam failure.
(HID BULBS) (Daytime LED's do come on & Daytime running lights.

Turn the **** on the headlight switch module and nothing. (best way to troubleshoot?)
No high beam obviously (same bulb)

2) Engine Fan runs continuously. As soon as the engine starts matter of fact. And runs non stop until a few minutes following key off.

3) Turn Signals & Cruise Control- If i plug in the cruise control switch, the turn signals stop working.
Reconnect the cruise control, neither turn signals nor cruise control function.

ARE THESE ITEMS CO- Related? Any feed back is much appreciated!!!!!!

Thanks, Christian

1. Can be ballasts. But If error code for headlight was registered more than 200 times it is completely disabled until code is cleared.
Any way you need to get wiring diagrams and check power and ground.
Have you checked 23,23 fuses on the CEM?

2. That can be because of faulty regulator or bad temperature sensor.

3. Can Be bad clockspring or bad SWM module.

Anyway to check any electrical components first you need to check if it gets power and ground.
