3/6/2009 · vectra c heater resistor keeps fusing WHY? Jump to Latest … the fan motor shaft rust’s due to water getting in,the rust then blows the resistor due to the fan having to work harder,strip the fan out,clean the shaft up and grease it. … i will do what erroneusbogz said clean it up and see what happens and cum to think of it the blower does …
11/30/2016 · If the resistor pack keeps blowing the thermal fuse, try not using fan speed 1, as this is the one that causes the resistor pack to be hottest (to slow the motor), and has least airflow to cool it. If it’s fine for a couple of weeks like that, then you know it’s an airflow issue. 24th January 2012, 10:36 #4.

I’m wondering if it is good/feasible solution to just bypass the resistor /harness and run power directly from the fan switch to the motor, through a fuse — like this: https://ibb.co/iBC7qV I realize this will limit the fan to only one speed, full blast, but its worth it to him to not have to keep screwing around with this.
7/17/2018 · Worn blower motor causes repeat blower motor resistor failure. However, other factors can cause the blower motor resistor to fail prematurely. For example. as a blower motor ages and wears, it can draw more current—more current than the blower motor resistor was designed to handle. In that case, the blower motor resistor will fail repeatedly.
High blower speed has direct power to the motor from the switch. If there is no power indicated on high blower speed, the problem is most likely the switch or the fuse. If there is power indicated on high blower speed, but not low or mid range, the problem is the blower resistor.
8/30/2017 · I guess the resistor pack drops the voltage for slower speed settings and thus current will ramp up very quickly if there’s any mechanical resistance in the blower fan .
If you only have one or two settings working on your blower the problem is generally at the resistor. The resistor is located down on the heater box under the blower motor. It can be reached through the passenger side fender well and is held on with two screws. Here is the resistor mounted in the heater box.
Ford blower motor resistor problems remain the most common solution to interior fan malfunctions on Ford cars and trucks. With that said, failed blower resistor assemblies don’t solve all of the possible failures. This is why at the bottom of the article we include a 2008 F150 blower motor wire diagram.
SOURCE: I have a 2005 chevy Treed55508, Try this solution. I have had the same issue three times. A Chevy tech told me that if it keeps doing it, to replace the blower motor, as it seems to be a chronic problem with the blower having to much resistance and thus burning out the resistors.
