look on the dash for a 4wd button or switch. may be located between the steering wheel and the radio. when you turn the knob to select 4hi, 4lo, 2hi, or auto, the indicator light above the corresponding selection will flash until the shift has completed. if the light stays flashing there is a fault in the 4wd system

Three possible causes are the blower motor itself stalling (worn out bearings), the blower control module (intermittent internal problem or bad connectors/wiring) or the HVAC control (switch if manual, module problem if automatic). I would start by checking for power at the motor when not working.

There isn't a fuse. There is a circuit breaker, but it runs all the windows.

Some run longer to finish the cooling process.

The valve itself is non-serviceable and the component must be replaced.

wheel bearings will not put the indicator on look for a bad wire connection or faulty actuator control or actuator the noise will be the unit trying to engage and slashing teeth

Betting it's your ignition switch. Whacky instrument problems is usually the ignition switch.

cam sensor it also linked to the crank sensor usually if the cam sensor fails around the same time the crank can become un synced with the replacement. or the new sensor is not the correct one, ie sensor from a 1998 model will sometimes work on a 2005 model if it has the same ecu fitted in the 2005 not the hole ecu but the chip. on the cam sensor there is say in some cases 3 poles positive feed negative and then signal. on all the poles there is a resistance between poles that the ecu reeds. it reads the voltage being used and the signal its receiving if one of these is wrong but it detects one of the readings being right it will think the other sensor is wrong. and thats a mis match. the resistance changes over time.

No, the 2 problems are not related, the SAI pump has no function while driving. Do not "flush" your transmission unless you want problems. Just change the filter and replace fluid with Dexron 6. Many people have had tranny problems with our platform after a full "flush". Your throttle position sensor may have problems, have it checked out for the shifting issues. Remember, the TPS is attached to the throttle body, not removable. Must replace whole throttle body, IF that's your issue.
