How to operate heated side mirrors - 2011 Dodge Journey

1999 blazer mirror problems. First I would replace the mirror. You can get an after market right side/left side, heated on eBay very cheap. that's where I get mine. They work fine. But you say the mechanic never fix your other problem in the first place. So I wouldn't no where to start. What is the other problem? Im just taking a guess here. But check your connections under your door pannel. Make sure no wires are bare or crushed. Make sure if any, fuses are not bad. Make sure your heat system that runs the heat to your mirror's is operating proper. You might have a short somewhere or maybe its just time to replace the mirror. To me when you see an amber color to your mirror it's the same as a light bulb blowing out or the mirror is getting to hot and shorted out. Good Luck.

I think you should go for manual first after that it would be easy for you to solve your problem. I had visited this site past 2 months before for my vehicle and find it quite helpful may be you will also get something useful here Best Manuals

Could have a DDS an PDS .depends on what RPO code yours has >

Heated Outside Rearview Mirror Operation
The REAR DEFOG relay controls the operation of the heated outside rearview mirrors. When rear window defogging is requested, the REAR DEFOG relay is energized and B+ is applied to the supply voltage circuit of the mirror heater element, located in the mirror face. A constant ground is also applied to the mirror face. Current will pass through the mirror heater element, warming the mirror, so long as the rear window defogger is commanded ON.

With
Heated Outside Rearview Mirror
The DDS and PDS control the activation of the mirror heaters. Upon receiving a serial data message indicating a request for heated mirrors, the DDS and PDS, will apply voltage to the mirror heater element supply voltage circuit. The mirror heaters will remain active until a new message is received indicating rear defogger is to be deactivated.
The power mirror system consists of the following components:
• Driver Door Switch (DDS)--An electronic control module with integrated switches and requires programming when replaced
• Passenger Door Switch (PDS)--An electronic control module with integrated switches, requires programming when replaced
• Power Mirror Direction Switch--Integrated into DDS and is a four position momentary switch that provides a signal input to the DDS for up, down, left/extend and right/retract with a mirror switch activation
• Mirror Select Switch--Integrated into DDS and is a three position switch that allows the operator to select the left or right mirror and also a neutral/fold position
• Mirror Extend/Retract Switch--Integrated into DDS and is a two position switch that allows the operator to select the mirror extend or mirror retract position
• Left Outside Power Mirror--Contains both the vertical and horizontal mirror motors
• Right Outside Power Mirror--Contains both the vertical and horizontal mirror motors
• Body Control Module--An electronic control module that requires programming when replaced, serves as the power mode master and is the main message handler
• Horizontal and Vertical Position Sensors, if equipped with memory mirrors--Supplied a 5-volt and low reference by the DDS/PDS and provide a variable voltage signal to the DDS/PDS that is proportional to mirror position
• Folding Mirror Motor, in each of the outside mirrors, if equipped with power fold mirrors--Provides extend and retract movements of the mirror and is serviced as a complete mirror assembly
Your best bet mite be to take to a qualified repair shop , i really don't think you'll be able to do anything with it.
Do you have wiring diagrams so you know which wires to test ,do you know how to do electrical testing ?
The Driver Door Switch (DDS) and Passenger Door Switch (PDS) supply voltage to the outside rearview mirror heater elements upon receipt of a serial data message from the HVAC module indicating that the rear defrost system is active. The door switch supplies B+ through the driver/passenger mirror heating element supply voltage circuit when a request is seen. Ground is applied through the driver/passenger mirror heating low reference circuit.

The is most likely the chemical that is injected between mirror layers that keeps the mirror from icing on a heated mirror. The seal has deteriorated due to age, most likely. It needs to be replaced with another of the same mirror or a non heated single layer mirror.

Installation
Heated mirrors

1. Connect the electrical connectors.

All mirrors

1. Position the exterior mirror glass on the exterior mirror motor.

1. Place a hand against the back of the exterior mirror housing and a hand flat against the exterior mirror glass. Press the glass in place until fully seated.

remove the broken glass with putty knife. go to a auto glass shop they can sell you a replacement heated mirror glass. the new glass is just glued to plastic housing in mirror and just plug in 2 little wires to back of glass were heat element is.hope this helps good luck.

Heated mirrors have a swtch in the car. That operates the eliment that is stuck to the glass.This eliment heats the mirror when turned on.It is used to defrost or demist the mirror.A none heated mirror has no wires going to it and no eliment at the back off the glass.OK.

could be a blown fuse. Take it into the dealership.. it's probably still under warranty!

Heated mirrors usually have a symbol on them -- a small diagram showing squigley heat lines.

If you don't see this, it's probably not heated. But when you take the mirror off, if it's heated it'll have wires connected to the back.

Yes, you can replace a heated mirror with non-heated -- just leave the wires tucked out of the way when you install the new mirror.

The exterior mirrors:

• are controlled by power controls on the LH front door trim panel.
• are of a foldaway design.
• may contain turn signal indicators.
• may be heated when the heated back window glass is activated.
• may have a programmable recall memory option.

Driver Seat Module
The power driver seat and power exterior mirrors are controlled by the driver seat module (DSM) only when the vehicle is equipped with the programmable/recall memory option.
---------------------------------------------------------------------
Power Exterior Mirror Operation
The power exterior mirrors are controlled by the DSM and are operational all the time, whether the ignition switch is on or off. Using the power exterior mirror switch, the driver can adjust the driver and passenger exterior mirrors four ways.
