Hvac blower motor resistor help!!

Ok, I have 2008 trd sport. My heater/ac would only work on hi everyday and sometimes the slower speeds randomly like has happened to many others on here... then last week it just stopped working at all for awhile then worked off and on. Sometimes smack it and it would work.

So I get help here finding the issue or what we think is the issue and I decide to do it myself with very little mechanics experience.
Today, I buy the resistor. Here's the old one and new one.

Im worried they're very different looking but it plugs right in.
Then, Nothing. Can't get it to even accidentally work. Checked some fuses but not all and they look fine. Took the new resistor out and put the old back in even and still nothing...

I'm just trying to figure out my next troubleshooting idea, the connector does look like this so now what should be my next plan?


@CurtB said I should ask you all so be gentle

 

Everyone's probably thinking, not this again hahaha

 

It would be best to replace that connector - that brownish stuff on the grey body and the wire shows it got really hot at one point. Its probably dirty and sooty inside, and the heat might have deformed the contacts, so there's a chance it would just happen again if you did get it working.

Hmm.

 

You can def see some burn on the second wire. Its possible its that and its also possible its your blower. I would try swapping fuses to be sure one isnt blown before digging any deeper. I've seen fuses that are blown and you can't tell by looking at them. Blower motor is the most expensive fix so I would save that for last.

 

WAT?? I never said be gentle!
From your pics it looks like that connector got hot. I suspect it needs replaced, and that old resister you had needs replaced anyway. They don't last.
Those guys I said I would tag, fing geniuses on electrical:
@Jimmyh
@Muddinfun

 

I would love to do that myself but not sure I'm qualified. I'm only YouTube certified Haha

 

So there's a bucnh of threads on this apparently

I'm not sure how big of a project you're looking for, but some people seem to have upgraded that to a 3rd gen version with a better connector: https://www.tacomaworld.com/threads/fan-speed-switch-not-working.70275/page-19#post-21703798

 

I will switch them out tomorrow and see if anything happens

 

Remember, hold on to the COOL end.


















(not like this)

 

Lol I'm not that much of a girl but that's funny

 

Yeah, I was getting a headache going through them all and some were old so there could be newer stuff maybe

 

I wouldn't run it too long that. If indeed the connector is janky, you'll have to do it all over again fairly soon.

 

You said start the thread I just asked them all to be gentle!

 

TacomaWorld is also a maze!

 

Well I'm a pro at changing the resistor out now so I got that going for me. Back hurts like hell though

 

@JennJenn I replaced mine last year with this kit from Amazon. It comes with the new plug and the resistor and just crimps on. Pretty easy to install and should fix your problem
