In this case, the original pump lasted a little over 12 years with about 64,000 miles on the odometer. Infamous Salmon relay - Has been replaced with no change 2. They have admitted that either of two temperature sensors are likely the cause.
Im currently thinking that if I replace the accumulator I should probably replace the pump at the same time, I don't want to go through the same labour costs in 50,000k's to get the pump replaced. Words can not describe the level of professionalism from Bryce. If it's constantly at 75ish then I think that explains why it is not charging.

However, perhaps the pump is working fine but the accumulator is not holding pressure long enough?
