Do I have to remove any other parts to get the water pump out of a 20032003manufacturing buick rendevous

GM Fuel Pump Relay Testing Watch this video ,all GM vehicles work the same way . Turn the key on ,the PCM will energize the fuel pump relay turning the fuel pump on for two seconds to prime the fuel system.

Electrical problem ! Unless your using cheap fuel pumps . Did you try a Delco GM fuel pump . Do a voltage drop test on fuel pump electrical circuir also amp draw . Testing Electric Fuel Pump Problems with Voltage Drop Test

most modern locks require a under window lock release ,they use part of the lower window or a guard to block you from using a slim jim

Did you check the air pump relay in the underhood fuse box ? The PCM energizes the relay turning on the air pump .

steady coolant leak could be coming from radiator hose at thermostat or water pump.check water pump weep hole and gasket for leak.check heater core hose leaks or look for leak at the radiator side containers.

make sure the cooling fans are working

no, it runs on the serpentine belt:

3.4L Engine

1. Before servicing the vehicle, refer to the Precautions Section.
2. Drain the coolant from the engine.
3. Remove or disconnect the following:
   
   Negative battery cable Serpentine drive belt guard Loosen the water pump pulley bolts Serpentine drive belt Water pump pulley Water pump Water pump gasket

To install:

1. Clean the gasket mounting surfaces.
2. Install or connect the following:
   
   Gasket Water pump. Torque the bolts to 89 inch lbs. (10 Nm). Water pump pulley and hand-tighten the bolts at this time Serpentine drive belt Water pump pulley bolts to 18 ft. lbs. (25 Nm) Serpentine drive belt guard
   
3. Fill the cooling system.
4. Start the engine and check for leaks, repair if necessary.
5. Road test the vehicle and verify there is no air in the cooling system.

If its a 3.4 or 3.1 liter the water pump is right in the front. Remove the serp belt, remove the four bolts that hold the pulley to the pump, remove the five/six bolts that hold the pump to the timing cover housing. remove the pump. Pay close attention to the orientation of the pump. It only goes on one way. Any other way and the bolt holes will not line up.

Clean the mating surface of all the gasket meterial, install the new pump, pulley, serpentine belt. Fill with coolant. Open the bleeder valves on the water pump bypass pipe and/or the t-stat housing if equipped. Close them when steady coolant comes out. Periodically check them to remove any air pocket that may occur while running the engine. Failure to bleed properly will cause the engine to overheat!!!

After is has run for 20 - 30 minutes and the fans have come on and there is no more air burping out of the radiator replace the radiator cap.

Install the new thermostat (make sure it is the right temp). This will allow for your coolant to stay long enough in the radiator to cool down.

If that does not fix it, check radiator cap, belt that turns the water pump and the water pump itself along with its pulley.

There is also the possibility that the coolant temperature sensor is giving off false readings, that the coolant system is clogged or your engine fan is not operating when it should be.

Here is a link to replace your buick rendevous car mirror as well for all buicks. http://auto-glass.com/carmirror/buick/index.htm
It pretty much explains from a to z on how to replace the mirror glass only on any buick. Good luck
