The poor quality clones have a problem with an internal failure of the ground circuit that travels from the seven wire connector through the resistor and out to the blower motor. We have dozens of cases of this happening.Sparkyhttps://www.blogger.com/profile/17054692818227773842noreply@blogger.comtag:blogger.com,1999:blog-7300638475669940520.post-91517450247391891272010-07-22T02:06:32.338-04:002010-07-22T02:06:32.338-04:00So, I replaced the blower motor resistor on my Sil...So, I replaced the blower motor resistor on my Silverado, and a couple weeks later a friend was driving and smelled something burning just before the fan went out again. The resistor wasn't melted as before, and it was still getting current to the blower, so I went ahead and replaced the blower motor itself, but it still wouldn't work. Any ideas before I pay a mechanic to fix it?Christopherhttps://www.blogger.com/profile/10484886147577025245noreply@blogger.comtag:blogger.com,1999:blog-7300638475669940520.post-40798988716626268132010-05-29T17:03:31.360-04:002010-05-29T17:03:31.360-04:00If the 40 amp, green blower fuse in the underhood ...If the 40 amp, green blower fuse in the underhood fuse box is good, then you have one of several things happening. Poor connection at orange or red wire at the seven wire connector at the blower resistor. A faulty relay within the resistor assembly. No power on the orange wire from the blower switch. No power on the red wire even though the BLWR fuse is good.Sparkyhttps://www.blogger.com/profile/17054692818227773842noreply@blogger.comtag:blogger.com,1999:blog-7300638475669940520.post-91623238902723893552010-05-29T15:12:27.314-04:002010-05-29T15:12:27.314-04:00Just wondering if you found that the BLWR fuse was...Just wondering if you found that the BLWR fuse was blown? My A/C works just fine, no problems at all, except when I put the dial in fan speed position 5. Then it shuts off, no fan at all in "5".<br /><br />Any ideas what's wrong? Doesn't sounds like the resistor block to me. And the large green 40A under hood fuse is not blown.<br /><br />It's 97 degrees today!<br /><br />Thanks you for the help!Anonymousnoreply@blogger.com
