2004 chevy crew blower motor resistor ?

11 posts in this topic

I have a 04 crew cab with 5.3 and I started to smell a burning rubber smell when the fan was on. I thought the blower motor was going out. Well I found out that the pigtail going to the resistor had melted into the resistor. Long story short I replaced the pigtail and the resistor and now I have a different problem. A/C and fan work great except (my fan has a 0-5 setting) when you turn fan to high speed setting (5) It works great at 1-2-3-4 but when you hit 5 it shuts off. Anyone have any ideas what happened?? Maybe I will just be happy to have 1-4 work. Thanks in advance.

I would try repacing the blower motor. Only one thing that could have burned up the resistor. I think it was drawing to much amperage and melted the wires. Better to be safe otherwise it is likely to happen agian. Hope this helps.

I had the same exact problem a couple months ago. I replaced the blower motor. resistor, a relay, the selector switch, only to find out they were not the problem. Had a mechanic look at it, and he fond it was the wire for the hi speed had gotten hot and burt for what ever reason. fixed the wire and worked great. Hope that helps and good luck

Or its the high speed fuse, which I am pretty sure is on a separate fuse than the other speeds.

Thanks for all the replies. Airjer- where is that fuse located I will start there. I will update if I figure this one out.

under hood fuse block. Possible a 40 amp fuse labeled blower motor.

has a fuse but the relay should be what is controlling the load. I would double check the resistor to make sure that you did not bend it when it went back into the housing. You can check the wire as noted above to see if it is burned. The load on that wire is so extreme at start up it will toast the connection in the plug. Good luck.

The resistors themselves are not part of the problem if the high speed is the only thing not working. I'm pretty sure we are talking about a manual HVAC system which has 5 individual blower speed settings. The highest bypasses all the resistors and supplies power to the coil of the high speed relay (which is part of the resistor assembly). The relay then closes the contacts which allows the blower motor to receive a separate power source just for the high speed blower operation. If the fuse is blown than there is no power for the blower to receive even if the relay is working.

Well I checked the fuse under the hood and it is blown (40 amp). So I will pick up a new one and replace tommorrow. Airjer you must really know your stuff. Thanks for the help-I wil let you know tommorrow if this fixes it.

    •   When someone gets to the personal aspect, whether it's me or someone else, I will challenge them and if they can justify what they have said about an individual --OK -- otherwise show me why, and if it is just their opinion say so. I'll accept that if it's their opinion.   There is nothing generic about an insult, an insult is an insult. What do you consider as a douchebag?
    • Not sure why people get so worked up about being called dummies, poopyheads and sons of bees.  Whatever, its generic insults and this is the internet.   But yeah, there's a line somewhere in the there that separates the real douchebags* from the rest of us.  You know it when you see it.   *Sorry if any douchebags felt personally attacked by being called douchebags.
    • I was addressing it to JigSawJimmy Peatmoss  response : That's an opinion, not anything more , so I let it go.
    • Created/Saved all these jobs, cut gajillions off AF1 costs, etc.  Ok, so how did the that work?  Usually these sort of dealings aren't totally one sided.  At least the carrier deal had a bunch of Pence fingerprints on tax incentives Trump took credit for.   I have doubts that King Cheeto just shows up and blows a bunch of smoke up assses and corporate executives are just like, "Yay!"   Is Trump's Twitter bully pulpit that powerful?  He randomly yells at Boeing and they just fold over for him?  I thought we realized Trump on Twitter is only for the LOLs.
    • Well hope the Trump supporters are having fun, seems those days are numbered. Turns out you can't just yell fake news at real news and make it go away. The Feds are closing in, and at best it seems Trump thinks throwing Manafort to the wolves might get them off his tail. Anywho, lots of news today.   The FBI has information that indicates associates of President Donald Trump communicated with suspected Russian operatives to possibly coordinate the release of information damaging to Hillary Clinton's campaign   McCain: Congress doesn't have 'credibility' to handle Russia probes    Because this happened - House Intelligence chair discloses classified intel in clumsy effort to validate Trump   Also this earlier in the day -  Former campaign manager Paul Manafort secretly worked for a Russian billionaire with a plan to "greatly benefit the Putin Government."     And in completely unrelated news - remember those Carrier jobs you bragged about Trump saving? Yeah, those jobs are gone. Carrier pocketed the tax breaks then screwed the workers anyway. Great negotiation there. http://www.nbcchicago.com/news/local/job-cuts-endure-at-indiana-factories-despite-trump-pressure-416511193.html
    •   Who are you addressing this to? I did not make the statement only re-posted it. I also don't find PEATMOSS's comment very humorous as well.   PEATMOSS said: This is still, by far, the funniest thing I have ever read on these threads in a decade.
    •   Anything you post on here from now on has no merit or credibility as far as I'm  concerned.  I wasn't even going to respond to this, but feel what you posted needed to be. If you wish to call my mother a dam, you will, the same as you called another persons mother that. I don't give a rats butt what your political views are, however when you start getting into personal attacks you had better look in a mirror. You don't probably don't know anyone on here personally, yet you attack someone on a personal bases, call there mother a dam and ridicule them because they had a lower portion of a leg amputated due to something they can control, but had no control whether they have the illness and sometime that illness makes you pay a price. BD2 has that illness he can control to a certain extent where he can lead a normal life, however there will be complications and from what I know of him he will accept that. I don't know DB2 personally, I've never met him, I've debated against some thing on this where he and I have had different views, I respect his opinions even though I disagree on many, BUT I SURE AS H--- DON"T ATTACK HIS ANCESTORY OR  ANY TYPE OF DISABILLITY
    • Yea yea all ya auld pharts would  pass out the minute she popped the first button!!
    • Would he get a free hoodie for his efforts?
    • Great to see this in Minnesota. Trout has been on my bucket list and will happen this year. The mix of largies and smalls really works for this show and plays into the guys heads. I was pulling for Hack. He's become one of my favorites. I think these guys are gaining a new appreciation for MN.  Except maybe the Lane Bros.
