Can you bypass the blower fan resistor, the resistor for this 1997 lasabre costs $340 5. It is a Vishay/Dale Wirewound Power Resistor part# HL-50-06Z 1 OHM 5% 50W You can purchase it here for $3.38. This means that the current running through the blower motor , and thus is speed is controlled by the resistor value. 23 Posts . The real world wire is going to have some resistance, and a tiny trickle of current will go through the resistor. A few days ago my front AC blower stopped working on 1,2 and 3 speeds and would turn on only at 4 but then shuts off the compressor. If everything is OK with the blower switch, on the A/C Heater control panel, the blower motor should run as you bypass each blower speed (in the indicated test steps below). Running direct power to the motor itself would just give you high speed all the time as theres nothing to resist the voltage and would draw a ton of power as you would be bypassing the blower motor relay. In some cases bad blower motor resistor may not even turn the blower motor fan as a result your fan will not work at all and there will be no air coming from the vents. The Heater Resistor is also known as the Resistor Pack or Rheostat. For example. 9 K resistor 22 K resistor 100 Ohm resistor 14 VoltAnd another note- motor START capacitors and motor RUN capacitors are internally different. A new blower motor resistor will cost you around $20 at the dealer. This test result tells you that the blower motor resistor is defective and needs to be replaced. Reduced airflow also causes the blower motor to work harder, draw more current and that can cause repeat blower motor resistor failures. This can be annoying, but troubleshooting is easy. The fuse is what usually blows. if it has no power and the motor doesnt run, the motor is bad. Unless I'm mistaken the resistor provides 4 different levels of resistance with one having 0 resistance. The blower motor can be hot wired to the battery using a fused wire and switch circuit. The reason that the blower only works on high is because when you select high on the blower motor switch- it sends the current directly to the blower motor, bypassing the blower motor resistor pack. Check the cabin air filter for clogging. And when you have the fan cranked up all the way in many vehicles, you will bypass the motor resistor all together because it's not needed to … The usual problems - Heater Blower Resistor and/or connector. Overheating. A blower motor without power will not be able to produce any air pressure, and as a result the heating and air conditioning system will … If you look at the wiring diagram for the Ford F150 below, you'll see that the high speed setting bypasses the resistor assembly completely. vic DAD NAS (N. Amer. Has your heater blower lost the "low" fan speed setting? If you start at the blower motor, and check resistance in the circuit, you will find the problem … I took some photos myself and combined with photos from bluebee. In the highest speed state, the blower resistor is bypassed completely and the fan is connected directly to the car's battery, which allows maximum current through the motor . The blower motor resistor is an electrical component that is a part of the vehicle's heating and air conditioning system. no, I would guess blower motor, high resistance in the brushes is requiring more current to get the fan to spin initially, then after spinning you can feed it the lower current. Top Here is what I used to replace mine. Since the resistor coils are mounted in the air duct (to help the disipate the heat generated) they are prone to corrosion. 9/4/2012 -- I have a 2005 Chevy silverado 1500 (5.3L) with automatic ac and a full center console. CASE 2: Continuity DOES NOT exist between some of the blower motor resistor terminals. Community Answer. electrolytic capacitor can sustain. I want to dedicate a thread for Trouble-shooting HVAC Blower Motor and FSR circuit wiring. I need to know which resistor I need exactly. Within the blower motor resistor assembly is a non-user serviceable thermal fuse. Dirt and grime can accumulate around the motor and prevent it from venting itself, causing heat to build up over time. Can you bypass a resistor? the resistor and the switch provide ground, so the blue/white wire should have power, and the blue/black wire should have NO power, if it does have power, then most likely the resistor is bad. With just a multimeter, you can find out if it’s time to get a replacement. The blower motor relay supplies power to this motor when you turn the switch to "on" that can sometimes fail. Mine has a 3 wire harness going to battery and controls. The voltage across the 100Ω resistor is going to be zero. When this happens, you may notice that you will not feel anything blowing out of the vents at all. Blower motor fuse blows repeatedly. For this test go to: TEST 2: Using A Jumper Wire To Bypass The Blower Resistor. There are also some on eBay that have the controls and indicator lights on pigtails so you can remote the module if space is tight. … Thanks April 18, 2011 Followup from the Pelican Staff: The next step I would try would be to put the voltmeter on the blower motor itself (if you can reach it and hotwire in there), to see what voltage is being applied directly to the motor. the blower resistor module is incorporated into the lead for the blower motor. I'm not sure if this is the right one. Your blower motor may overheat because of a number of reasons. 2014 Flex Limited in Tuxedo Black, 303a with all options. The motor wears out over time, and can’t push as much air, leaving you wondering what happened to the air power. One of the first signs of blower motor failure is weak airflow. It is responsible for controlling the blower motor’s fan speed. If your car’s blower has only 4 or 5 different speed settings, it likely uses a simple electric resistor to control the fan’s speed. And the other is the 2 wire harness going directly out of the resistor to the blower. Your next step is to bypass the blower resistor using a simple jumper wire. If the resistor pack was done you would have nothing but "high" which essentially bypasses the resistors and connects the switch directly to the blower motor. A wire in the left circuit is shorting the 100Ω resistor . These would be the wires going TO the resistor. It's worth noting that when you turn the fan off completely, then there will be no power flowing to the blower motor resistor. This also decreases the efficiency of the defroster, as it uses the same fan. Arctic Whitewash Brush-tone Grey I'll go one step further and say that if you're blower motor works on high and you have the card type Ford blower motor resistor, no further diagnosis is required. SOURCE: Blower motor on 96 Isuzu Rodeo does not blow on if fuses are good, check for power at blower motor, when truck is running and a/c on.
