Why won't the Lexus side mirrors retract automatically?
4 Answers
Lexus side mirrors won't retract automatically due to: 1. Damaged mirror adjustment motor; 2. Poor contact in the speed limit connector. The Lexus is a mid-to-large-sized sedan with a 4-door, 5-seat configuration. Its body dimensions are: length 4975mm, width 1866mm, height 1447mm, wheelbase 2870mm, fuel tank capacity 60.6 liters, and trunk capacity 454 liters. The Lexus is equipped with a 2.5L naturally aspirated engine producing maximum power of 131kW at 5700rpm and maximum torque of 221Nm, paired with an electronic continuously variable transmission. It features MacPherson strut front suspension and multi-link independent rear suspension.
I've driven a Lexus for many years and have encountered several instances where the side mirrors wouldn't auto-fold. The last time was after winter rain and snow—the mirrors didn't move when I pressed the lock button. Upon inspection, I suspected poor contact in the switch button or internal motor short-circuiting due to water ingress. Increased resistance from aging wiring could also trigger the fault. The auto-folding mechanism relies on small motors, and rough handling or external force can easily jam the gears. Blown fuses are a common issue—check the fuse box and replace if needed. I recommend prompt inspection to prevent escalation, such as scanning the control module with a diagnostic tool at a professional shop. I usually keep the mirrors clean to avoid dirt clogging the joints, as proper maintenance extends their lifespan. Safety-wise, unfolded mirrors are prone to scratches when parked, so don't overlook this. My advice: try toggling the switch repeatedly, manually fold and lubricate, or perform low-cost maintenance first.
As an everyday car enthusiast, I've found that the inability to retract Lexus power mirrors is often an issue with the electrical control system. The core components involved are the switch, control unit, and folding motor: if the switch signal is interrupted, the motor burns out, or there's a short circuit in the wiring, the function fails. The fuse that protects the circuit is an easy point to check, located in the fuse box under the driver's seat, and replacing it isn't costly. Another possibility is oxidized or vibration-loosened connectors causing unstable current. When testing myself, I use a multimeter to measure voltage differences for easier diagnosis. It's advisable not to force the folding mechanism to avoid damaging the gear system. Pay attention to waterproof sealing during car washes or rainy days to prevent water ingress and short circuits. Regularly inspect wire insulation and replace if aged to avoid major repair hassles. If the control module fails—a common issue in Lexus—reflashing the program or replacement requires professional tools, so visiting a reliable repair shop is prudent. Improper handling could damage other components, increasing expenses.
When I first got my Lexus, I noticed the side mirrors weren’t folding automatically, which worried me, especially in tight parking spaces where they might get hit. The check is simple: first, see if the switch responds—if the light doesn’t come on, check the fuse; replace if blown. It could also be due to motor overheating jamming or a lost control signal. Common causes include water ingress after washing or dust clogging the gears. My approach was to test the function manually—if no response, take it to the shop. The technician said contact issues in wiring can be fixed cheaply with cleaner, while motor replacement costs more. For safety, if mirrors don’t fold, check surroundings before opening doors to avoid scratches. Keeping the car dry helps prevent issues. Simple maintenance saves hassle.
