Yes this sounds right, and at $170.00, I think they are selling you the entire motor assy. The resistors should only be around $30. The last one I bought was from Auto Value.

Blower motor resistor
I have a 2005 trailblazer ext, my blower motor resistor is going bad. Does any one know where i can buy one? I called around some of the part store's and they said they don't carry them yet for my year. Called a chevy parts dealer and they want $170 dollars, does that sound right? I pulled the part down from under my dash never unplugged it, but notice rust on it. I cleaned up the rust with a piece of sand paper, turned it on and it worked but 5 did not, I could live with out 5 for a while, but laiter the next day it went out again, so I assume I need to replace it does that sound right?

No they aren’t just resistors anymore. It’s a printed circuit board and yes they are that expensive.
Cheaper at the parts stores by about 70 bucks if you can find one. I had to replace one on a friends 01 impala. If I remember it was around 100 buck at NAPA.

I can't find one anywhere, but the chevy dealer. napa it is 24.95 but they don't have any and the factory they get them from doesn't have one. I called late model salvage yards and they don't have them either. Do you think a garge that works on cars would have one and be cheaper than a dealer? Any body know where else to try? Could I add soder to it and make it work?
More Trouble
I found a dealer that had one for 50 bucks, I bought it and went to put it in and 2 wires the red and the black in the big (7 wire) harness was melted just a little through the connector and the red and black prong was burned, tried to clean it up a little and hooked up the new one but it still doesn't work. I followed that wire harness as far as I could, it goes behind the radio. I am almost positive it goes through the firewall and into the engine compartment. Where do I go from here? what is the problem?

Re: More Trouble.
I have a 2003 Trailblazer and am having the similar blower motor difficulties. Was able to get the resistor from the local parts store for about $28, but neither it nor the motor are the source of the problem. Looks like we have to get the vehicle wiring diagram and trace it back to the control panel. The burned red and black wires show that too much current was being drawn by the blower motor and that should be the subject of a separate investigation.

You'd think that they get this right eventually... I have a 1998 Malibu that had the same issue. The parts were 30 bucks from the local Advance Auto Parts (they were the only ones who had it)... The hardest part was getting it out...

Only place that i could find one was the local dealer. Under 30 bucks.
You guys should check and see if this is a recall item. At the very least it may you should file a complaint there.

same issue
I have the same issue as the guy below, my blower stopped working. Pulled out the resistor, and it looks fien, but the wiring harness coneected to it is melted to the resistor. Can i salvage the resistor and buy a wiring harness to tie in to it? Or do i need to buy a new resistor and wiring harness? Has any one bought one, i don't know if it comes with the wiring harness.

I had the same problem with my 2007 TB, luckily I still had 500 K on the waranty and it was coveredf. They replaced the resistor but wouldnt look into why the wires were melted, so if someone xomes across the cause please let me know
I fixed the problem for now. I pulled the resistor out, turned on the car with help(someone holding the resistor so it doesn't burn anything) I turned the speeds up and down and your help moves the harness around to see if its a loose connection( if the harness is melted). When i got to speed 4 my help noticed the wire was getting warm and at speed 5 burned his hand(melting the harness). for now i run on speed 3 or less i have had no problems. ( but the problem is still there) I followed the red wire up and removed electrical tape and found that the red wire was reduced from thick to thinner going into the harness. That explains the heat. I plain on buying a new harness, matching the thickness of the wire, already have resistor and maybe replace the blowermotor ( might be drawing to much current) but for now i have drove it for about a year with out any problems (speed 3 and under).
yous guys should get us some good pice of the part you are working with, you can get resistors from radio shack. if they are a common resistor, you may be able to cut the old one out and solder a new one in. get a pic. the resistors a color coded to represent their resistive values.
I had the same problem with a 03 Grand Am, and a 1997 F150. What is so hard about making those things to last? I just got a 05 chevy Trailblazer and now I'm just waiting for it to go bad.
Solution
To All
If you have one of the fowling model GM vehicles this is the procedure for fixing a blower motor not working properly.
You will need to replace both the Blower Motor Resistor and the 7 pin conector that plugs into the resistor at the same time to solve the problem correctly. I do not what parts stores are avbiable in your area but I have included the BWD part number for the harness connector and the resistor. 7 pin harness connector is BWD PT5793 brand Part number is and the resistor is BWD brand Part number RU1064 replace both of these at the same time will resolve your problem.
