Perfect replacement. Repair completed.
Perfect fit part came on time no complaints
Working fine for a year or so. Sure recommend.
Easy to install. Works like it should.
Great product. The instructional video that goes with it is excellent.
As always A1auto delivers the goods. Great replacement to oem. Fast shipping and free. Cost was fare and low compared to other sites. Thank you.
The resistor is working fine after a couple weeks. I replaced with OEM parts for the connector and blower motor. Couldnt see spending so much more for this resistor. I would suggest getting your own insulated but splicers of varying sizes for the connector and not dealing with the shrink wrap.
This was perfect and it worked and then it stopped so we found another fault in the wiring harness
Was the perfect part. Everything works perfectly now.
