7500 with some codes ap at 5g 5j 8l

all the relays are fine... every time I shut her down I get code 8l, 5g, 5j, ap, and at...if I unplug my k4 relay she works fine , but then I cant bring her in the freezer because my 8m will pop up after I drop below 40 degrees. think this is more of a VM issue or a relay card itself ? Anyone else run into this before ?

Hi, I've had this codes a few times in 7500 reaches and 4250 pacers
one of the relays on the fuse card has welded tips and when you pull it off they unweld and it works again for awhile

if you look real close at the relay female pins, they may be burned slightly. Pull all relays and look close for any differences. You need a new fuse/ relay card. Check back in 7400 posts, lots of info.
