Can this be done
October 3, 2020
overall pretty good instructions, could have been better on power source, need better wiring harness for full sized truck too short, relay and splices too close to switch hard to get into dash.heater pads easy install and work really great once powered up, recommend 1/2 day each seat need time
Works as advertised
November 10, 2020
I threw these into a Buick Encore with relatively little trouble. Any trouble I had was with finding a place to power these in the car itself, so that's nothing to do with the heaters. They heat well, and there was plenty of cable to reach pretty much anywhere in the car if I needed it.
Customer Q&A
Ask a question to 1A Auto customers who purchased the product
Is this a wire or ceramic heater?
March 3, 2017
This will be a wire heater.
March 3, 2017
wire. I didn't realize it was a universa seat warmer so you do have to run new switches that are supplied I took the seats out each one took about an hour and a half to do it works fine
March 3, 2017
Wire. I do like it though. Quick and hot.
March 4, 2017
What was the tool that was included for? I didn't see it used in the video.
January 16, 2018
Tool is used to crimp rings around the seat fabric if factory seat had any crimps holding the fabric to the seat frame.
January 16, 2018
What is the WATTAGE of these heaters? I am comparing to heated seat covers which I found in one description are 32 Watts, but have not been able to find any wattage information for any aftermarket seat heater kits.
December 28, 2020
We do not have that info available for these.
