1999 jetta overheats until heat is on full blast

You should start by checking the thermostat for the radiator. It controls the flow of coolant to your engine. Turning on the heater allows the coolant to circulate through another type of radiator. You should also check your radiator fluid to make sure you have enough( the fluid should be changed around every 5 years).

Where exactly is the thermostat on a 88 jetta, i believe it is a 1.6L 16 valve.

VW family engine thermostat is behind the lower coolant inlet . It will be either a plastic or aluminum housing.

To find engine lid and look down at bottom of radiator. You will see a rubber hose from the base of the radiator to the engine at the left side looking in. The hose is attached to the housing that holds in the thermostat.

FYI. Never run a VW engine without a thermostat in place or overheating will occur ....really !
