For what it's worth, The 95 I had, 390, had fantastic heat with the dash unit. The 99, 512, has lukewarm dash heat. Also, the 95 would heat the AH during cold weather drives to above 150, the 99 struggles to heat the AH above 120 in cold weather driving.
The difference? The 95 had a circulation pump that boosted the water flow through the manifold that sends coolant forward to the dash, and to the AH. There was a micro switch on the heater controls that turned the pump on when the heat control was all the way to hot.
This may not be the whole story, but it's the limited data I have.
