SOURCE: The gear shift lever on

check the brake light circuit (do the brake lights work), this is what provides power to unlock the shifter, it is called the brake park interlock and is one of the new DOT safety devices..

Look next to the blower. You can remove the panel under the passenger side. Go through the glove box and move it down out of the way to access the electrical connector. Then remove two bolts and the electrical connector.

SOURCE: NEED TO REPLACE BLOWER RESISITOR. FAN ONLY WORKS ON HIGH SPEED

Under the dashboard on the passenger side you will see the blower motor. Near the blower motor inside the air duct is the resistor. It should be held in place by two screws. Hope this helps. Good luck

You will need a special wrench that is thin. With the belt still on hit the end of the wrench with a dead blow hammer. Some fan clutches are reverse thread.

If fluid level in trans is ok it sounds like clutches in tranny or internal pressures are going bad.

Shifts rough in 1st gear and lose overdrive at times


on the older style blazers the fan clutches did fail and would often be misdiagnosed as shifting problems as the clutch engaged and disengaged.... also a hard 1-2 shift can be due to your vehicle storing a transmission fault code in the ecm... some transmission fault codes will put the transmission into a fail safe or limp mode in which it engages high line pressure .... this can cause your hard 1-2 shift and will feel normal most of the time other than that. high mileage on the transmission fluid may also require it to be flushed and have the filter kit replaced

I just purchaced a 2001 ford ranger 3.0 and was wondering if it is normal for the cooling fan to rev high. you can hear it roar when you start out but when it shifts gears it quiets down. i also noticed...


Is normal for older vehicles to do this. Wait until something breaks and fix it. I know it doesnt sound like great advice, but if all is working,leave it alone.
