Does anybody have a wiring diagram for 1994 Buick Regal? i need it for the cooling fans. My pass side cooling fan isn't coming on when the A/C is on and the temp starts to get hot. I changed the relay. that didn't work. I also check the connection with a test light that didn't work. I assumed the relay was bad since the test light didn't light up. At this point I need the diagram so I can see if I tested the right connection

R/F door trim will have to be removed. Most likely you will find linkage disconnected from the inside latch of the outside door handle. You might even find a broken piece of the door handle requiring replacement

More than likely (and we will hope) it is the oil sending unit. In comparison it is a very cheap and quick fix to replacing the oil pump. Auto Zone has a pretty good componet location section that has tips for replacement if you cant find the sending unit or the oil pump. Try that first it may save you a lot of work.

If the outside temp.sensor is reading -38 degrees then this is what is causing the compressor not to come on.You need to check the wiring to the outside temp.sensor and the sensor.Make sure it is connected.It is located on the front grill area.Between the grill and the bumper cover.Hope this helps.Good luck.
