1999 - 2007 chevrolet truck and suv blower motor resistor

So your blower motor only works on high now? any lower speed you feel nothing , youve checked fuses? well then it is a good assumption your blower motor resistor is the culprit. there are a few ways to check and see if this is your issue . so lets talk about it!

first of all the blower motor resistor slows down voltage or current to the 12-14volt blower motor thats why high setting has no resistance so it wants full voltage and amps. to get a lower setting of speed the resistor forces voltage lower by turning  excess of the demand into heat. this is why they dont last forever but are usually cooled down by the air stream in the hvac assembly. So if your blower motor works on high only or you have some lower speeds that dont work its safe to assume that the resistor is the issue.
to test this you can use a DVOM(digital variable ohm multi-meter) to measure the volts DC to see if your getting voltage at all settings from the power connector that connects to the blower directly. one is a positive connection the other the negative connection as long as you dont put your leads for the meter in the same one your good , if the polarity is reversed you will see -12v if you flip it you should see 12 volts or +12v , start with the highest setting to see if power is there. this will confirm you have a direct power source from the switch (with ignition on of course) then go to your lowest setting your values on a good resistor will range from 1v-12v as you go through the settings if you have variable voltage readings on the resistor that slowly rise with the selector its operating properly.
If no its time to replace the resistor because it has failed. on the chevrolet trucks and full size suvs its a very simple process. if you would like a video demonstration on this your in luck Joe The Auto Guy has uploaded on on this issue and its very easy to follow directions so here is the video

Chevy truck window regulater replacement

hey guys whats going on? finally have another vid out and this one is popular as it takes place in a wide selection of vehicles from gm. 1999-2007 gm trucks and suvs full size. but the process is pretty easy to tackle in an hour or so for a novice approach. the video is of the window regulator front door replacement. Tools you will need are a
10mm socket,
7mm socket ,
3 inch extension or driver.
trim tool helps but a wide flat head screw driver works as well
and a ratchet for sockets
regulators are found on the internet from 40-150 dollars U.S. plus shipping and or your local parts dealer this includes the window motor
heres the vid hope it helps ya

gm transmission line removal

So if you have worked on gm doing radiators or just line removal you have seen the quick disconnect on these lines and some people are afraid to touch them thinking they will break. but they are actually really easy as long as you have a a nice sharp pick and a little patience. so i show you just how easy it can be to get these clips off .
I deal with these alot with transmission removals and engine changes(usually in the way).  so again i made a quick video on just how easy these clips are

late upload

so thursday is a late upload and it is taking a longer than normal to upload. i will update this page with a link soon as it goes through . the video is of a gm abs light issue . its an easy fix most times when the bearing isnt bad.   http://youtu.be/APA04ZAMUJ0
      earlier this week i filmed a charging system test on how to check the alternator but il try to have it finished and uploaded next week
