you should be adding the 134a to the system the low pressure switch is doing its job by not allowing the compressor to kick on, it wont kick on until there is enough 134a in the system to be above the preset pressure for the low pressure switch.

3.3L?
Looking at the engine from front (right side of the Van): Stating at the Top, Going Left to Right and Clockwise:
Over the Alternator
To under the Idle Pulley,
To Over the AC Compressor.
To the Left Side of the Water Pump.
To the Right side and Under the Crankshaft Pulley
To the Right side and Over and Down the Tensioner
To Under the Power Steering Pump
And Back up-to the Left side of the Alternator.
Advise when puting it on:
Put the Belt around everything else accept for the Alternator. After it is around all the rest of the Pulleys - Pull the belt up - tight from the Power steering Pump and the Idle Pulley to form a loop, holding the Belt close to the Altenator Pulley.
Using the 15mm wrench or belt tensioner bar - rotate the Tensioner Pulley towards the front of the Van and then place the belt over the Alternator.
