Front HVAC blower motor intermittent

[02Lightning]

Starting to sound like the control module possibly?

Any idea where that is located?

I have looked at them, all look good. No traces of heat.

I mean the harness that plugs into the blower motor? the tip can get burned inside, mine was partially melted inside from the outside it looked fine, but when I pulled the motor out and looked in the slot you could see it. all it takes is a little bit and it makes the motor stop working.

Yep, well aware it gets hot there and melts. I paid close attention when I took it apart. All looked good.

well intermittent issues are a real b*tch, if you have a junkyard around I would throw a used blower motor at anyway just to see. the hvac modules are not cheap and "might" need programming, mine did. it worked but the rear would only blow warm if it was set to 90, put it on 89 and it would blow ice cold after a crap load of troubleshooting turned out it just needed to be programmed to to my vin.

if you buy a blower motor online be sure it is the right one there are 2 versions. the earlier models had a slot for cold air to blow on the motor from the hvac box, the later models were self cooling and the hvac box did not have the hole for the air. a later version motor may still fit but you would have to plug that hole.

and just looked at rockauto at the motors and there information is incorrect, shows both motors but the description/crossover years is wrong, shows same info for both motors
lol, in fact all there blower motor info for 2007 a tahoe is all f-k up

I've already installed a new motor and still have the problem. It was the wrong version motor but fit no problem.

well that just leaves the control module or some kind of funky electrical issue.
to bad it doesn't happen often enough that you could watch the hvac feedback with the scanner and see if it is a environmental sensor going goofy or whatever the case may be
have you tried swapping the front & rear environmental sensors? new ones are only about $25 or were last time I checked.

I have not tried that, not sure how to get at it. You have a part number?

you can reach inside the headliner on the drivers side one pretty easily, the rear passenger one takes a little more work pulling the headliner down the reach it.

I first thought, it was my phone microphone.. ( Until I learned what that little black attachment was on my overhead control )

ya it's a pretty common misconception for people to think it is mic or "big brother" is listening, which he is but not from there.

No big brother inside my '05.... I removed the 'On Star' box and replaced it with the "Blue Star" box to make all phone calls with out an outside connection. ( Works perfect )

but... what about a mobile phone? credit cards/atm card or anything with a rf tag. hell anymore they just use plate readers.
cash, carefully painted face, learn to walk differently (gait) and some one else's car is the only way to avoid it
not to go off course on his post but there is a reason why every baby born in a medical facility has there foot print taken, no different than a fingerprint

 

[mountie]

On my Android phone.... I shut of the mic ( "talk to text" , etc. )
Most smartphones mic are 'always listening'.....
I avoid apps , etc.... I can't stop everything, but I do what I can...

it's funny how we feel like that but every day someone walks up and does some crime right in front of a camera and no one seems to be able to stop it. in all these decent neighborhood in tx, every 3rd idiot with a pickup truck has a gun left in their truck at night with the door unlocked. kids just pick random trucks at night to walk up to, check for unlocked doors to find guns and walk away. ring cameras get video, I sware some just wave when the light turns on, go back to checking doors and walk away.

cops don't care they just tell people that have been hit that they will move to another neighborhood soon and not to worry about it. but here we are worrying about our phones app being able to target market what we are talking about. like we are in the middle of some giant scheme out to get us all.

what a time to be alive.

ya I personally do not have many worries about being listened in on or marketed to because of it, but when it creates a obstacle to say employment because of a post I made online or a video I uploaded that wasn't a act of terrorism, ******, etc and was simply my "opinion" on whatever then it becomes a problem.
or being restricted access to buying car insurance or whatever kind of stupid crap they are trying to pull now.
robberies and shootings and things like that may or may not be reduced or solved any faster, intelligence plays a part
the half-way smart ones steal a car and do what there going to do and dump it, burn it, sink it in a lake whatever
the AI stuff may get way out of hand before people go hey wait a minute..... of course it will always work in favor of the law.
it's already worked it's way into some court cases and then they got caught providing false or misleading data.
I know people that have changed there names on social media simply because they didn't want there personal information, post's etc showing up when a employer searched for it
i mean who really cares if I like Brazilian donkey s*x or red headed step sisters? or I like to watch terrorist blow themselves to bits and pieces by accident. that has no bearing on anything.
now if like to wear womens clothes and wear them to work dressed like a clown and steal peoples luggage and control nuclear stuff, well........ maybe that's not so good.
