If you plug in a code reader you may have a P0480 code stored. The low speed cooling fans not coming on but yet when the temp goes high the high speed comes on is most often fixed by replacing the cooling fan relay which is a solid state relay located attached with a rivet to the front bumper beam behind the grille area and down.

plug in a code reader and read the code or codes. Why did you replace the fuel pump? A guess? I need codes to tell you the next step.

Air Mix/Mode Actuator (Blend Door)

1999-00 models use cables to actuate the temperature door and re-circulation doors.

The blend door is a servo responsible for controlling the mix of warm air from the heater core and cool air from the A/C and outside.

Or
Insufficient coolant , trapped air in the cooling system might not have enough coolant to full fill the heater core.
The hot coolant flows from the engine to the heater core through the "inlet" hose. After circulating through the core, the coolant returns to the water pump through the "outlet" or "return" hose. Both the inlet and outlet return hoses should feel hot when the engine is at normal operating temperature and the heater is on.

1. If the both heater core hoses were cooled, then this vehicle might have an insufficient coolant in the cooling system.
2. If the heater core inlet hose is hot and the outlet hose is cool, the heater core might be clogged.

Note: check the radiator coolant level and top it off as needed.

Try switching the high beam relay with the low beam relay in the Power Distribution Center under the hood and if that solves it then buy a new relay.

Where is the location of the leak? Sounds like it could be a hose.

Yes the water pump is likely if the leak is under that area.

The neutral safety switch / range sensor is usually mounted on the transmission near the shift lever.

thanks for the enfow

First question - how many miles on the engine? Second, about how many miles are driven between adding the oil? Are these mostly highway or city (stop and go) miles? Third, are you certain the oil is 'burning' and not leaking from the engine at some point?
Depending on the age and mileage / condition of the engine - using one quart every 6 weeks may not be considered excessive. You should really measure in miles driven rather than time, however.

Check the radiator coolant level, if it is low, then there is a possibility of a head blown gasket.

A leaky head gasket can allow coolant to seep into the engine's cylinders or crankcase. Symptoms include a loss of coolant with no visible external leaks, and white steam in the exhaust, especially after restarting the engine when it has sit for awhile. A leaky head gasket can be diagnosed by pressure testing the cooling system, or by using a "block checker" that pulls air from the cooling system into a cylinder that contains a special blue colored leak detection liquid. If there are any combustion gases in the coolant, the color of the liquid inside the detector will change from blue to green. A leaky head gasket can often be temporarily sealed by adding a sealer product to the cooling system. But for bad leaks or ones that cannot be stopped with sealer, the head gasket has to be replaced.

Connect an OBD 2 device and see if there is a communication with the powertrain control module.

Then, post a reply to the add answer for further assistance.

Note: if there is no communication with the pcm, then, negotiate with the local parts stores to get a loaner for a try.
