Re: need to replace Mirror Assembly, 03 suburban
Your going to have to remove the inside door panel to get to the three bolts that hold the out side mirror assembly. Once you have the door panel off you'll see the three bolts that hold the mirror assembly, just un-bolt and un-clip the wire harness to the electric/heated mirror. To install the new mirror assembly, just do everything in reveres. Go to Auto Zone and by extra door panel clips, there is a good chance of breaking some of the retainer clips and Auto Zone will have the step by step instructions to replacing the mirror assembly and the removal to the door panel. Good luck and keep me posted. Be glad to help.

I recently tried the DIY service and repair manuals from a website and it actually helped me repair transmission problem in my jcb 3cx site-master. It would'nt move forward or reverse, engine was good both
solenoids for forward and reverse worked, but still couldn't diagnose the problem.
I don't have much technical knowledge but I just followed it step-wise, and now it works perfect! covers wiring, codes, diagrams, torque specs, PCV, everything
got it from www.reliable-store.com
not too hard, behind the mirror on the inside there should be a triangular plastic cover, this will unclip with a little bit of levering with a screwdriver or flat blade.
once removed you should see a few holes in the door frame, in a few of those holes you will see at least 3 bolt heads, undo the bolts making sure you dont drop them inside the door cavity, there will also be a multi wire electric plug that you will have to seperate, the outside mirror can now be removed.
Dont try just replacing the glass as it involves almost destroying the whole mirror assembly, replace the complete mirror assembly
I apologize if this is insulting but heated mirrors were an option in this model and unless you specified a heated mirror when obtaining the replacement part then you may have a mirror that eventhough the plugs (connections) fit, it doesnt ahve a heating element to warm the mirror itself. Do you on the glass surface of the mirror have a box with waves coming out of top of it or some resemblance of such. This indicates heat and thus the presence of a heated mirror assembly. Otherwise you will need to check your invoice if you purchased from a parts provider. If you obtained from a used parts location (junk yard) you may have gotten a cosmetic similar model that doesnt have all the functionality of your previous mirror.
Power windows an locks work ok ? Do you know anything about automotive electeronic control modules ?
Power Mirror System
Power Mirror System Components
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 4 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 3 position switch that allows the operator to select the left or right mirror and also a neutral/fold 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
• Memory Switch, if equipped with memory mirrors--Supplied power by the DDS and provides a voltage signal to the DDS upon a switch activation
• 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
• Powertrain Control Module (PCM), if equipped with memory mirrors--An electronic control module that requires programming when replaced and provides the message indicating transmission gear selection
• Driver Information Center (DIC), if equipped with memory mirrors--Part of the instrument cluster which is a an electronic control module that requires programming when replaced and is used to personalize the memory recall functions
• Fold 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
Each of the outside power mirrors contains 2 reversible motors to provide horizontal and vertical movement of the mirror glass. The vertical motor operates the up and down directions and the horizontal motor operates the left and right directions. If equipped with power folding mirrors, each outside power mirror will contain a reversible fold motor to operate the extend and retract functions. Each of the mirror motors are circuit breaker protected.
Do you know what DTC'S - diagnostic trouble codes are ?
The driver door switch (DDS) and front passenger door switch (PDS) each contain switches that control power door lock and window functions. The DDS also contains the control switch for the power outside rear view mirrors. These switches are integrated within the door control modules and are not serviceable as separate components. The DDS and PDS monitor these switch inputs for internal faults and set B1023 00 if any are detected.
You could have any number of problems an without testing , hooking up a scanner that can check DTC'S in the door module ,electrical circuit testing etc... we'd only be guessing . Your best bet mite be to take it to a qualified repair shop.
It's not that hard to replace the passenger side mirror. You will be able to do it yourself. I will tell you how. Remove the screw holding the molding to the base of the mirror and remove the molding. Remove the screws and detach the mirror. (if it is electric mirror just unplug the electrical connector. Installation is the reverse of removal. Hope this will help you.
You can usually just replace the mirror, any commercial auto-glass store has the glass you need. sometimes it is necessary to replace the mirror and its backing (a plastic frame which snaps into the adjustable motor) you don't need to replace the whole mirror unless the housing is broken.
the mirror sits on a circular clip if u push against the middle it might click into place if not turn mirror all the way in towards the right so u have finger room stick hand behind mirror and pull forward will release keep hold if it if you have heated mirror disconnect the two wires
