United StatesExcellent part good instructions
United StatesGood. The shipment arrived as expected Have not used the part yet so i am unable to comment on the product itself
United StatesI was surprised that changing the OEM mirrors would create a "check engine light" warning. Turns out the passenger side mirror has the outside temperature that you see on the dash. This is connected to the computer which then creates the error. Boost Auto Parts has the add on part to correct this condition. After the part was installed the check engine light turned off but the outside temperature read minus 40 degrees. After a quick email explaining the condition, the solution is to drive the vehicle. It take about 30 minutes to recalibrated. Thanks
United StatesEasy to install....Worked great!!
