my seat belt sometimes will lock up at start up .does not make any diff if you wait on lite to go our or not really is a hassel sometimes might have to kill and restart 4 or 5 times not to say sorta embarising also 99 sport 2500 200,000 still stock and still strong

 

May I ask what you mean by lockup??

 

I didn't realize there was anything electrical to "lock up".

 

shoulder belt locks up just as in a accident

 

there is no electrical connections to those seat belts at all, just removed a set from a pair of seats i got from a junkyard and gave them to a buddy. my guess is that youre pulling on it too quick or at such an angle that its tricking the spring loaded retractor to lock and making it think that an accident has happened. trying pulling real slow and make sure its a continuous pull, dont jerk it.

 

Also the angle the truck and seat are at might play a role in the lock up. Mine tend to do that sometimes because of steep angle the truck is sitting in or the angle of the seat back.

 

There most certainly are electrical connections to '98 and '99 seat belts. It was the only years that Dodge used them -- they have something called a Seat Belt Control Module screwed to the underside of the middle seat. Dodge did away with them with the 2000 MY trucks because they were so problematic. My shop manual shows a diagnostic procedure to check what's wrong but it's pretty complicated (remove the IOD fuse and then push it back in, while sitting in the truck with the doors closed, push in cigar lighter and turn the ignition off and on 3 times, etc.) -- didn't work for me as mine are still locked up. I'm about ready to by-pass the thing. Even tried buying a SBCM from a junk yard, but it still doesn't work. I'm open to any other ideas.

 

never had any problem with mine besides pulling too quick and it then locking
just make sure ya wear it, unfortunately ya never know when it will save your life

 

If you have a '98 or '99 and you never had the problem, consider yourself lucky. It's a fairly common problem from what I understand.

 

mine just locked up! i gave me problems for a few days both did the same thing at the same time now both will not come out i guess its the module i cant find any thing about it in a repair manual
