Question about 1999 Chevrolet S-10 Pickup

1 Answer

99 S-10 P/U - Blower squeaking like a banshee

I believe it's my blower fan next to the heater core (in the engine bay on the outside of the firewall.) I can feel a small vibration in the motor housing (when I can bear the noise) and have to assume it is the fan because when I disconnect the power connector, no noise. I can still feel the heat so I know the heater core is not going out.

If there are bearings in the motor, is it possible to just remove the blower and somehow relube it? Or do I have to just replace the blower.
My truck is just over 100K, runs great, but don't want to spend a lot more on it. Thanks for any help.

You will probably have to replace the motor they are usually sealed units. You might be able to get oil to one of the bushings but it will not last too long, it's probably worn out.

The heater a/c or defroster will not work in my car no air will blow through the vents


Is the fan turning (do you hear it)? If it's blowing, but not passing the blend door, then that would describe why it doesn't deliver air to the passenger compartment.

Poor Heater System Performance CAUTION
Check all fluid levels and adjust as needed, before operating vehicle for extended periods at idle.
  1. Start the engine.
  2. Idle the engine until the thermostat opens (upper radiator hose will be hot) Is the engine at normal operating temperature (approx. 200° F)? If yes, go to the next step. If no, go to step 16.
  3. Set the mode selector to FLOOR mode.
  4. Set the heater control selector to the warmest temperature setting.
  5. Set the blower speed the lowest setting.
  6. Carefully feel the inlet and outlet heater hoses at the heater core. Is the inlet heater hose significantly hotter than the outlet heater hose? If yes, go to step 14. If no, go to the next step.
  7. Set the mode selector to PANEL mode.
  8. Select the maximum blower speed.
  9. Select the warmest temperature setting.
  10. Place a thermometer into the center I/P PANEL air outlet and affix a second thermometer to the heater core outlet heater hose.
  11. Record the temperature at the center I/P PANEL air outlet and at the heater core outlet heater hose. Are the two temperature readings about equal? If yes, go to the next step. If no, go to step 13.
  12. Inspect and repair the cowl, cowl area, recirculation door, and the HVAC evaporator/heater core case for cold air leaks. Repair any problems found, go to step 17.
  13. Inspect the temperature door operation. Repair any problems found, go to step 17.
  14. Turn OFF the engine. Back-flush the heater core. Start the engine. Select the FLOOR mode and the lowest blower speed. Select the warmest temperature setting. Feel the temperature of the inlet and outlet heater hoses at the heater core. Is the inlet heater hose feel significantly hotter than the outlet heater hose? If yes, go to the next step. If no, go to step 17.
  15. Replace the heater core. When the repair is completed, go to step 17.
  16. Check for low engine temperature problems, Repair or replace as needed, go to step 17.
  17. Operate the system in order to verify the repair. If the system operates properly, the repair is complete. If the heater still does not work properly, repeat the entire procedure.
Insufficient Defrosting CAUTION
Check all fluid levels and adjust as needed, before operating vehicle for extended periods at idle.
  1. Start the engine, select the DEFROST mode, and select the maximum blower speed. Does sufficient air flow from the defroster outlets? If yes, go to the next step. If there is insufficient airflow, go to step 9.
  2. Measure the engine operating temperature. Does the engine reach normal operating temperature (approx. 200° F)? If yes, go to the next step. If the engine does not reach normal operating temperature, go to step 7.
  3. Select the minimum blower speed. Select the warmest temperature setting. Carefully feel the inlet and outlet heater hoses at the heater core. Is the inlet heater hose significantly hotter than the outlet heater hose? If yes, go to step 10. If the hose temperature feels approx. the same, go to the next step.
  4. Test the operation of the A/C compressor clutch. Does the A/C compressor clutch engage? If yes, go to step 6. If the compressor clutch does not engage, go to step 5.
  5. Inspect A/C compressor clutch and controls. Repair or replace as needed, go to step 13.
  6. Determine if the A/C system is operating within specifications. If yes, go to step 8. If no, go to step 11.
  7. Check the low engine temperature problem. Repair any problems found, go to step 13.
  8. Inspect for correct operation of the recirculation door. If the door is operating correctly, go to step 13. If the door is not operating properly, go to step 12.
  9. Check air delivery system. Repair any problems found, go to step 13.
  10. Check the heater core for blockage. Repair or replace as needed, go to step 13.
  11. Check A/C performance. Repair or replace as needed, go to step 13.
  12. Repair the recirculation door concern. When the repair is complete, go to step 13.
  13. Operate the system in order to verify the repair. If the system is operating properly, the procedure is complete. If the system is still not providing proper defrosting, repeat the entire test.
Noise from Blower Motor
  1. Inspect the air inlet grille for debris. If the grille has debris, go to step 7. If the grille is clear, go to the next step.
  2. From inside the vehicle, close all vehicle doors and windows, turn ON the ignition, with the engine OFF, and cycle the blower motor through all speeds in order to determine where and when the noise occurs. If noise is heard during the blower operation, go to step 3. If there is no noise, go to step 10.
  3. Inspect for excessive vibration at each blower motor speed by feeling the blower case. If there is vibration, go to step 5. If no vibration is present, go to the next step.
  4. Listen to the blower motor at each blower speed. Is the blower motor making a squeaking or chirping noise? If yes, go to step 8. If no noise exists, go to step 10.
  5. Remove the blower motor, and inspect the blower motor and impeller for deposits of foreign material. If there is debris, go to step 7. If there is no debris, go to the next step.
  6. Inspect the blower motor impeller for cracked blades, loose impeller retainer, or improper impeller alignment. If any of these conditions exist, go to step 8. If none of these exist, go to step 9.
  7. Remove the foreign material, go to step 10.
  8. Repair or replace blower motor or impeller as needed, go to step 10.
  9. Install the blower motor, go to step 10.
  10. Operate the system in order to verify the repair. If the condition has been corrected, the repair is complete. If noise still exists, repeat the entire procedure.

2002 crown victoria blower fan quit.All speeds


There is a module on the fire wall of the passenger side engine bay. It's a $20 part. it is just below the heater core hoses that go into the firewall (2 of them, easier access by removing, watch for antifreeze spill) there will be a rectangular plastic piece with a plug coming out of it approximately 3-4 inches wide with 2 screws. use a 7mm (i believe) socket to remove. This is a "BLOWER MOTOR RESISTOR" order from ford or online, replace the resistor by unplugging the old one and putting in the new one. Watch for burnt cracked plugs. You may need the plug too, but if you can get around it, just hard wire it directly in place where the pins line up.

1998 Ford Contour. The heater blower stopped suddenly. I checked all the fuses, good. I removed the blower and hooked it to 12 volts. Whoosh! It almost spun out of my hand. I checked the plug into the...


I dont know what these other guys are saying..I think they snif the glue!!! YOUR BLOWER FAN ASSEMBLY CAN EASILY BE REMOVED !!
1. Remove the wire
2.Find the "tab on the housing and pull it down while rotating the fan housing counter clockwise. This will remove the fan assembly. Plage 12 volts on the contacts to test the motor. If it works then the resister pack is blown. On the fan housing (near firewall ) you will see a plug going into a square looking box with a screw in it. Remove the wire then remove the screw to remove the resistor pack.. A new resistor pack is around 20 dollars at a ford dealer. Hope thie "FREE" info helps!
