The relay is not your problem or it would blow wheather or not the heater motor was plugged in or not if it was shorted,you need a new heater motor.

Hi , I have a 2009 Ford E250 van and all of a sudden the switch that controls the blower motor doesnt activate the blower. I have heat if the vehicle is moving , but its not blowing heat from the vent


There is a fuse, may not be solely for the blower but it has to be fuseed! Anyway I would suggest checking all fuse's both inside and outside boxes first then locate blower relay swoop with the one next to it and test blower if its stil not working its the fan speed switch! They gave trouble on previous models! ! You'd be very unlucky for a 2009 fan motor to fail...good luck.

Heater/acblower fan doesn't work on high. Other fan speeds work ok. what is the problem? It's a 2003 chevy astro van


Hi, check fuse 12 first. If it is good, you will need to replace the blower resistor. The high speed relay is built into the resistor. The resistor is next to the blower motor and looks like the picture below. There is a connector in the resistor and the 2-wire connector coming out of the resistor attaches to the blower. The blower is usually under the dash above the passenger's feet. You may have to remove a kick panel to see the motor and resistor. Please let us know if you have any questions, and thanks for using FixYa.

Cant find relay or fuse for blower motor...1991 chevy astro van


this is common the fuse is located in the fuse box but the common problem with these is the blower resisitor, this is located next to the blower and is screwed into heater box, a quick test is to check for power and ground to blower first and check fuses located under the dash on the driverside. also check under the hood in the engine compartment for another fuse/relay box hope this helps.

1997 Isuzu Rodeo V6 4X4. I have only owned this vehicle for 3wks and the fan/ac wont blow at all out the vents. The blue light comes on when i push the ac button but that is all it does. I don't know which...


C-19 Blower motor fuse 25A located in cabin fuse box. Left hand footwell on LHD vehicles, right hand dashboard on RHD vehicles.
Start by checking blower relay B-36 in the engine compartment fuse and relay box. Remove the relay. Jumper directly from battery to pins 85 and 86. (also see here: http://www.fixya.com/cars/r5544622-wire_relay if you dont know about relays) The relay should click Now measure across pins 30 and 87. Measurement should be 0 ohm.
Remove the blower motor(3 screws on the bottom of the unit under the passenger side dash) and connect jumper leads from the battery directly to the blower motor to see that it operates.
The blower motor resister is mounted on the ducting between the motor housing and the heating unit. Remove to test
Measure :
  • pin 1-2 : 2.4 ohm
  • pin 2-4 : 0.9 ohm
  • pin 2-6 : 0.28 ohm
  • pin 2-3 : 0 ohm

2005 Chevy astro van, 4.3L A/c, Blower motor,


It could be a bad blower motor - tap on the blower motor with the end of a hammer when you have the switch in the on position - if it comes on then it is a bad blower motor. If it doesn't come on I would check to make sure you are getting power and ground to the HVAC control head.

1998 Astro Van Heater AC Blower only works on medium & Low


Yes, in high it bypasses the resistor and uses a high blower relay. But I think on 1998 Astro the High relay and the resistor are built together. It should be mounted in the blower box real close to the blower motor.
