The vacuum hose operates the mode selector not the fan. If you lost vacuum you would have only defrost and no other settings but the fan would still work. When the fan doesn't work and you tap on the lower part of the dash board, will it begin to work again? Sometimes blower motors can be intermittent so simply hooking up power to it on a bench and seeing it spin doesn't completely rule it out as the culprit. I would check the connections at the motor, resistor pack and speed control knob. If all checks out it's probably a bad blower motor.

2002 grand caravan blower motor intermittent replaced resistor


in review
the fan speed resistor is new
you bench tested the blower motor
12 volts test ..only runs it at full speed
if cabin filer want changed the blower motor would run hotter

could be the motor brushes or bush/motor bearing when slowed
you might want to inspect the brushes and clean the dust out of the motor
if no better
does that have climate control ?
might be the fan switch itself or the earth isnt so good

Blower fan not working


The resistor bank is bad for slow speeds, the switch is bad for high speed. In your test, you have voltage, but the switch wont carry the amps, to run high speed. Open circuits will not blow fuses. Replace both switch and resistor bank for all speeds. Make sure to clean leaves and trash from fan housing and see if fan spins freely.

1997 Aerostar 4 liter engine has miss on several cylinders. New wires and plugs. Miss is intermintent. Usually worse under load. At times van runs fine.


check for vacume leaks on intake and other vacume hoses. random misfire is also usually a clogged fuel filter or pressure regulator. could also be a cam or knock sensor. are their any trouble codes.

No air flow on heat or cool from blower motor, new blower motor, cleaned all coils


there is a small vacum hose from on top of the motor to a junction of hoses on the passanger side behind the ww washer holder. It could be cracked or broken, although this defaults to high spped of the fan on defrost only. NO air flow can be a blown fan fuse...blocked doors...etc

Blower working on top 2 settings but no air comeing from vents


Hi

Thanks for using FixYa. The possible causes due to which the blower is not working normally are fuse, blower resistor or a bad blower motor. Test the voltage at the blower with a test light. Please check the motor relay switch fuse under the dashboard. Use a multi meter to measure ohms for continuity. If these are fine, bypass the blower motor relay switch to make sure blower motor is running fine. Motor relay switch is right next to radiator fan relay switch under the hood. Pull out the blower motor relay switch to see 4 female pin holes. Test the relay switch using a 12 volts power source and a multi meter to measure continuity. If fan works after jumping the pin holes, then blower motor is fine but relay switch may be faulty. You may also need to replace the blower motor resistor. If still the problem persists, then you need to replace the blower motor.

Please do rate the solution and revert for further assistance.


Thanks

No heat 1995 cutlass ciera


Ok quick fix........
This is a common GM problem. The heater will stop operating when the plastic vacume line is broken under the hood. It is an 1/8 inch black plastic vacume line running fron the intake manifold to a vacume check valve under the hood to the heater/AC assy located to the passenger side. You may also want to check the fuses under the dash to the blower motor. If the fuse is good take a Digital multi meter and check for voltage at the motor. If there is no voltage check the reistat in the blower hosing. It is a small rectangle plastic piece on the blower housing with two small screws. Check for voltage at the input and output side. If there is voltage check for resistance at the motor by unpluging the blower motor and probing the terminals to the motor. Tap the motor and see what type of fluctuation you get. Lastly if all that checks out and you have no voltage to the motor or reistat check the switch input and all three fan speed outputs. It could be a simple switch issue.
Good luck and let me know if you need further guidence.

Loud noise


It sounds like the blower motor for the heater is shot, either bearings in the fan or electrical melt down. It's ok to drive it w/ fan off, but if u need your defroster you'll be in trouble, have a cloth ready in case u need to wipe condensation off the windows so u can see. You'll have to have the blower motor checked out to see if it's the bearings, if it is u can have it replaced. countrycurt0
