Possibly... but before you do anything drastic, a simple question:
When you open the valve on the tank... do you just crank it wide open quickly, or do you open it s-l-o-w-l-y??
There's a safety built into the regulators that are pressure sensitive. If it detects pressure too quickly, it sees that as a potential leak, and begins to shut itself down. And, though the other side works ok, some regulators are more sensitive than others.
Try the following. It sounds dumb, but in many cases it works.:
Close the valves on both tanks (so the regulators reset themselves)... and leave them off for at least 15 minutes. (I go for a half hour myself)
Then go out and SLOWLY open the valve on the side that's giving you trouble (driver's?). One turn, then wait 5 seconds.... another turn, another 5 seconds... etc until it's fully open. Then go inside the rig and see if the problem has persists. If so, then you may have a hardware issue. If not, you now have your solution.
