Easy install

This was easily the quickest install of a blower I have ever done. About 15 min total. Put that with the fast shipping and it was great.

I have a 2008 Isuzu Ascender that it's AC Blower went bad on me and started to smell burnt. I TEST it and sure enough it was no good. I went online to buy it from 1A Auto, the price was excellent and a few days it arrived. I installed and it works just like the factories unit or even better. It's been two years that I have installed the blower and it's working perfectly with no issues. Keep up the good work 1A Auto, consumers you can't go wrong with 1A Auto, their prices and warranty are excellent.
Good for the Price

A while back the blower resistor went out on my dad's 2005 chevy trailblazer when I had gone through to test the resistor I had also noticed that the blower motor was falling apart. So I ordered the blower motor from 1AAuto and have not had any complaints.

Prior to replacing the blower motor, the only way to get it to run was to lower the glove box door all the way and whack the motor with a plastic ice scraper LOL!! Easy replacement and now no more whacking the motor!!!

Third fan motor in a 2003 Trailblazer Car came complete with a mouse It likes the small hole into the fan motor I am surprised that it has been in there when I turn on the fan! This is a different fan/motor and I think the mouse is gone: Good price and great service

This blower motor is very quiet. I was worried about buying this. The original housing has a hose into the blower motor used for cooling. This blower takes care of that issue. They added a duct to the back of the housing that goes were the hose would of been. Wish they had mentioned it in the description. I was hesitant to buy it for this reason. This company has the products, prices, videos & customer service. Truly a great company. Bought many products from them with no issues at all.
Customer Q&A
How do you know it is a bad motor? I put a multi meter to connector and I have 10 volts, not 12 volts. Could it be the resistor? The fan does not work on any setting. Thank you for any help you can share.

You can pull it out and try running it on a 12v power supply. I am no electronics expert, so don't know how to read multimeters, but it's pretty easy to remove the motor.

Best way to determine if it is the blower motor is to run a jumper wire directly from the motor to your battery if it runs they more likey your resitor it ealier to do with motor out of the car if its not to mush trouble this is the way i check all my blower motors works 100% of the time anymore ?'s just ask

You are right. Check the resistor. In my case I ended up with a spare fan motor after similar symptoms. once you remove the resistor you should be able to see if it's blown.

My old squirrel cage motor squeaked after a valve job and the new one is a bit quieter. It might be the switch since mine won't run all the time on the high setting (5) but improved with the new one.

In my case I had no blowers. I checked the electrical it was fine. So I just replaced the blower motor rather the check the resister. It was an easy install

Sounds like bad motor. I was able to pull my motor and apply voltage directly to motor to confirm. Need to secure /anchor the motor housing before applying power. If contacts are corroded, it could prevent motor from working. Once the motor is out, you could inspect the brushes. My motor was intermittent due to very worn brushes. Not clear that you can get replacement brushes.

It is very likely the resistor however the motor may have incurred damage from the faulty resistor. I suggest that you direct wire a battery charger to the motor to see if it even will turn over first. Be sure to disconnect the motor wires from the vehicle first. Then order the appropriate parts.

I thought it was the resistor but I had a garage try to figure it out and he said it was the motor. I think you should try a different motor and I think that should solve your problem.
