Question about 1994 Pontiac Grand Prix
What mechanical work has been performed on the vehicle recently ?. As most problems that occur after a recent repair was made can be traced back to the area of where the repair was made.
It is suggested to start by inspecting all of the wiring connectors near the blower motor for burnt electrical contacts in the connectors. Next I would proceed to the engine compartment and look for the same things. next would be to inspect all of the fusible links that are usually loacted where the battery cable attaches to the starter.
Think back and try and remember if any work entailed disconnecting any electrical harness connectors as this is usually the fault area..
However please check the bellow procedure...
Start the car and turn the air conditioning on. Allow the engine to run a few minutes so the air can cool. Check to make sure you have the proper buttons selected. This simple step may uncover the root of the problem.
See if the problem is as simple as a blown fuse. It is probably a blown fuse if the temperature controls on the dashboard seem to work correctly but have no effect on the air. Find the fuse box in a Pontiac Grand Prix inside the glove box. Locate a small bin on the right side of the glove box and open it. The fuse controlling AC will be in location 28.
Check the control panel if the climate controls on the dashboard do not feel right. First disconnect the black negative cable and wait two minutes to disable the air bag. Remove the entire instrument trim panel, which extends the entire length of the dashboard. Find the control panel behind the radio. Remove the screws holding it into place. Unplug the electrical connector and pull the control panel out.
Adjust the air levels with the controls as the car is running. Listen for the customary blowing noise. If you cannot hear it, or it does not increase when the air is turned to high, then the problem is likely the blower motor. First disconnect and remove the instrument panel. The blower motor is found on the passenger side behind another trim panel. Unscrew to remove it.
