Question about 2001 GMC Savana Cargo
On my 2001 gmc savana van I am having issue with the a/c compressor turning on and off I have replaced the compressor and both high and low sensor but the compressor keeps turning on and off making my van idle bad what can be causing this?
The ac compressor is controlled by the thermostat connected to the evaporator under the dash When the cab air temperature reaches the set temperature the ac compressor switches off . IT is called cycling. If it causing a problem with the engine rpms then there is a sensor problem not an ac problem so run the fault codes to determine where it is . ECM's are programmed to maintain constant rpm regardless of the load placed on the engine at idle.

could be a bad fuel pump, or fuel pump relay. they are having problems(a lot) with the ethanol in the gas on GM products.Fuel pumps sales are through the roof at parts house on GM's. Have a pressure check on your fuel system. That is probably it. Add a can of Seafoam to your fuel every 3000 miles to alleviate this problem.

On the inside trim, you can remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. Then you'll need to manipulate the panel and disconnect the door handle linkage from the door handle and disconnect the wiring for your controls

look under the hood on the right side where your brake fluid is..There is a black box to the farest right of the brake fluid. take off the lid to this box were you will find fuses..Reach in and feel the fuses to see if any are loose.The largest fuses in the front, push down on those and then try to start it up..Take them out look at them make sure there ok if this dont work..they the one bad might need to be replaced..
