If that fuse is okay. try giving the wiper motor a jolt by whacking it end on with a broom handle. Can you hear the wiper motor running? Check the linkages.
There is a fuse for the ignition control module , fuse #13 ELEC/ENG 15amp . in the under hood fuse box . The odds of the fuse being bad are astronomical . More likely that ignition module or a crankshaft position sensor is bad . There are videos on youtube on how to test gm ignition systems .
If you are referring to the suspension air pump, it is automatic and will only operate if necessary to re-level the vehicle. If the vehicle is not leveling properly, check the level sensor at the rear axle for proper operation.
The engine thermistat is located on the front of the engine, top side, but it tucked under, so it is hard to get at. You may need to replace the thermistat. Have a mechanic do it if you're not comfortable with it.
Sounds definitly like a fuse or a relay. If you have owners Manuel it will point out which fuse/ relay to replace. Remember, if a fuse blows there's a reason for it that needs to be remedied
DO A SPARK TEST USING A SPARK TESTER AND USE A FUEL PRESSURE TESTER GAUGE TO DO A FUEL PRESSURE TEST.FUEL PRESSURE SHOULD BE 41 TO 47 PSI.IF YOU GETTING NO SPARK.CHECK THE IGNITION MODULE FUSE.IF FUSE IS GOOD.SCAN IT TO CHECK FOR IGNITION MODULE FAULT CODE.PCM FAULT CODE CRANKSHAFT SENSOR + CAMSHAFT SENSOR CODE.IF YOUR FUEL PRESSURE IS 0 CHECK FUEL PUMP AND FUEL INJECTOR FUSES AND RELAY.IF OKAY FUEL PUMP FAULTY.BY USING A SCANNER IT WILL SAVE YOU TIME AND MONEY.NEW FUEL PUMP ABOUT $300.00 AND A NEW IGNITION MODULE ABOUT $200.00.
I had the same problem on my 2004 Rendezvous with both front and rear wipers not working. Thanks to AutoZone I found free wiring diagrams on their website. Fuses 29 and 32 were good. YouTube videos suggested checking relays. The problem was fixed by interchanging Accessory Relay 27 with the same type of relay, Relay 20, the Rear Defogger relay. I ordered a new relay, plus a spare for $30 from Amazon.
look for rear wiper fuse and relay.because both circuits is tie together . look in glove compartment for the manual .it will show where all fuses and relays located.
