The Standard Ignition MRS148 door remote mirror switch is made for vehicles equipped with power folding mirrors and, on certain applications, memory seats and heated mirrors. This part number is used to restore driver-side mirror adjustment control when the original switch becomes worn, intermittent, or nonresponsive. It cross-references AC Delco 22756623 and RMS148 for the same application.

Use MRS148 when you need a replacement switch for Cadillac ATS, Cadillac CTS, Cadillac XTS, Cadillac SRX, or Chevrolet Impala models listed in the fitment data. The OE-style design helps maintain the original look and electrical connection expected in the vehicle.
