Ive been searching and searching and cant really find an exact answer to these issues. She usually sits for about a week before i take her out. Its been really rainy here lately too. I dont drive her in the rain if ik can help it. It started out friday night with no problems. I was cruising down the interstate and something was missing. Voila! No HUD. I got to my destination and started searching on here for a possible fix. I checked fuses 19 and 25 and they were good. I put the key in and all of a sudden the HUD is working again. I didnt think too much more into it. I was leaving a few hours later, the HUD is working still but when i would take off the car would shutoff (2MPH). No message in the DIC or anything. No codes but a U1000-H in the TCS system. Luckily my wife had her key and i tried it and away i went. The HUD went out about a mile down the road and never came back on.

The next day i went out and tried starting her with the key that was giving issues and the same thing happend. I put my wifes key in and now i get the pull key, wait 10 seconds message followed by Service Column lock. The car would still go and the column would never lock and i cleared out the messages. The HUD would go in and out while driving. The last time it came on( about 2 minutes) The engine speed would not show but everything else would. I tried paging but it would just change ECT and EOP. I sprayed a little contact cleaner in the ign switch and now both keys seem to be working fine but the HUD is acting up still.

Any advice is greatly appreciated. And i have a CLB on order. The recall for the CL was done several years ago. Shouldnt the column lock if i get that message? Could these 2 issues be related? Thanks Again.

 

I have some codes in the left and right door modules (they are historic)from when i replaced the window motors. The only other system that has a code was the TCS and the code was U1000- H. The battery is over 6 years old.

 

Ill be changing the battery this weekend and installing the CLB. Thanks for your help! Will keep updated.

 

While you are at it, check the passenger footwell for damp carpet and if you find it, better start looking at the BCM and find out if its dry or not
