We commonly see
2001-2005 Workhorse W20-W22's blowing the PCM/TCM fuse. This is caused by a failure in the power supply circuit of the TCM. To verify the TCM has failed, just unplug the TCM
and see if the fuse still blows when the ignition is turned on. If it continues
to blow then you most likely have a wiring issue.
This is a REPAIR SERVICE for TCM’s that are experiencing the above issue. If you do not have time to
wait for the repair service, you may purchase the TCM outright and if it meets the above
criteria, you can send in your TCM to see if it is eligible for us to “Buy Back” your TCM for $200.
