I have a 97 Jetta GLS with the 2.0

My power locks are not working. I'm fairly certain that its the vacuum pump. However my budget is very limited so I want to be sure that its the pump before I go ahead and buy a new one.

I have pulled the pump and checked voltages at the connector, however I can not find any reference at to what each pin should read out.

Can anyone help me with this? :confused: Maybe measure the voltages from working model, with the switch depressed in both unlock and lock and while as resting.
