Ford Repair Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.
The GEM module should not be to blame here. The brittle wiring or circuit board on the instrument cluster is more likely to blame. I recommend getting the cluster back out and confirming its getting power and ground. If that is something you can do, I have the wire diagrams to help you.
This is my 1st answer of what can be many. You the website and myself expect you to have a ~~~5 STAR EXCELLENT~~~ experience with my help. At the top of your screen is the rating box that you only get to use once. Please make sure to complete the mandatory rating when ready or reply and say "I am pleased with my answer". Not rating or rating 1-2 stars does not benefit you nor me in any way.
Sorry was towing most of the day.
The fuse box CJB would be more so to blame than the GEM. Can you remove the CJB and GEM to see if your leak has gotten inside either and caused rust and electrical arcing?
At the cluster can you confirm the 2 RD/YE wires are power with the key on.
RED/WH power all the time
PK/OG and BK/WH grounds
PK is pink
Hello again Chris here,
Thanks for the update.
As I mentioned before this post is due to time out, that is tomorrow at 9pm.
That means you will have paid for help but not resolved the concern and it means I will not get anything for helping.
Rating the post is the only way to prevent it from closing. Rating does not stop the conversation between us.
My goal is to help customers and get rated in return since this is my income and a rating is the only way I get paid. If you do not want to rate me, I can opt out and let others help.
As I mentioned rating keeps a post from closing, it does not close the post. You have already paid all the fees to get this question answered. Rating good , bad, or not at all does not effect that already processed fee.
Can you verify by number which fuses are not powered?
Fuse 16 is only powered with the high beams on, is that when you checked this fuse for power?
Fuse 21 is only powered while the key is held in the start position so the engine will crank, is that when you checked this fuse for power?
Fuse 20 is only powered while the key is held in the start position so the engine will crank, is that when you checked this fuse for power?
Have you confirmed when starting the vehicle that fuse #20 is not briefly powering up already? No your steps I do not believe will tell you if the GEM is bad. Do you have a scan tool to check the GEM?
Would you like the instrument cluster diagram to see everything it needs to work?
You should be able to scan all modules to see if there are GEM codes stored or the inability to communicate with it.
No communication with the GEM means the GEM is not getting power or ground or the GEM module is bad.
I am on vacation till Wed and replying from my phone now. I can opt out to let someone help now if you can not wait?
Okay, reply on Wednesday evening or later
I honestly do not know what else to say nor offer. I can opt out or I can send you Ford wire diagrams or pinpoint tests. I just do not believe I can diagnose this not being there in person. What would you like me to do?
In this link are all the diagrams I have access to. Each one opens up into 1 or many sheets of diagrams. Which sections would you like.
