2004 Holiday Vacationer Blower Motor Resistor

HVAC blower motor not working. Have ruled out issue with fuses all good, relay good ( replaced it anyway). Next step would be blower motor resister pack replacement.

Can someone help me locate that resister for my 2004 Holiday a Vacationer?

Thanks in advance for any assistance received

The resistor packs are usually mounted on the blower housing on the outside of the firewall near the blower motor. A couple of screws and wiring terminals can be removed to change out the resistor pack. A local automotive supply house should have the resistor pack if it is determined it is defective.

The blower should run on high even if that resistor pack is bad? Have you located the blower and checked for voltage there?

If/when you get it working on high, when it comes to that resistor, many times it's more about the wiring connections than it is the resistor itself. You get a little corrosion going, then you get heat, and then you're cleaning up the results of both.

Agree on the location. Normally it will be pretty easy to access.

Thanks

I actually found the location of the resister by tracing back from the motor location to as you mention the back of the motor under the hood mounted on the blower shroud. Removed it, however locating a replacement required ordering on line due it being discontinued.

Now, I see one post indicated that the fan should work on high even if the resister is bad. In my situation it don't work at all. If the resistor ends up not being the issue, what would be the next step, the dash switch?

Thanks again, this is a great forum!

The question I would want answered prior to making my next move, would be regarding whether or not the blower motor has power going to it?

In other words, even if you replace the resistor, if that motor is burnt up, or has a bad ground (not unheard of!) it's still not going to run.....

Regarding that ground wire, many/most blower motors only have the one power wire leading to them. For it to work, there's a second (seperate) wire leading to them, that's plugged into a tab located somewhere on the blower motor, or leading to one of the blower motor mounting screws. If the motor has power going to it, and is not running, this ground wire could be your issue.

Sorry to complicate, but I hate to see people tossing parts at an issue when a little trouble shooting might point to a 30 second fix?

For people that can't use a volt meter, a simple test light you can get at the auto supply can save you a bunch of money. Easy way to see if power is at the motor or not. Touch it at one side of a connector and the other side will show you if the connection is bad in the connector. I am not big on just buying parts. I have seen guys at work (where parts are free) just change out everything until it works.
