Front and rear blower motors stopped working together need advice

Front and rear blower motors stopped working at the same time 2004 Tahoe need some advice

 

[OR VietVet]

Welcome to the forum.

Need to look for what is common to both of them. Have you checked fuses and relays? Your owners manual should have these locations and commonalities listed in there literature. Need to always start with the basics. There are many threads here about problems with the blower motor resistors and the harnesses. Any warnings of problems before they stopped or it all happened at once?

Working when I shut the truck off when I started the truck up and drove neither would work check the fuses checked all the connections I am baffled why both of them stopped I am not a mechanic but I'm a certified ASE body tech so I do know somewhat about the mechanics but I can't seem to come up with a reason why both units would not work

I purchased this Tahoe 5 years ago from a 72-year-old woman who had bought it new in 2004 it is in beautiful shape but an electrical nightmare

@swathdiver may have some input for you. As stated by @OR VietVet above, start with the basics in troubleshooting and factor in the fact that both blower motors stopped working at the same time. I don't know for sure, but I believe that each blower motor has its own fuse.

I believe that the source could be the main controller. At least that's where I'd start with my Tech-2. Does it light up? Could it be Murphy's Law and that both resistors went kaput at the same time? Stranger things have happened.

Do you have power at either blower motor with switch on.do you have power at resistors with switch on.Do you have power at relay with switch on-do some more trouble shooting.
