Estimate the cost for replacing a dash harness for module 2003 GMC Sonoma.
You do not say if you plan to do the replacement yourself or if you plan to have it done at a shop so it's difficult to answer properly.
Harnesses are very expensive - - yours will be over $500 for the complete unit - and labor for electrical work is very high and that cost is also based on where you live. different areas could mean a difference in labor costs of a lot of money.
If planning to take it to a shop you should take it to at least 3 difference shops (dealer?) and ask for estimates but be sure all information is written down.
If you're planning to do the work yourself then you should go online or call several auto parts stores in your area to find out the current cost.
There are several different types of wiring harness for this car. You have an Aftermarket Radio Wiring Harness with OEM Plug that sells for around 5-35 dollars depending on which one you actually want. There are also factory wiring harnesses that have the plugs for radios included and these are selling for around 40 dollars. There are other types of wiring harnesses for your car but in general, they deal with the parts that are made for adding a radio to your car. You are sort of vague about the type of harness you are looking for and need to have replaced. I am thinking this is for your dashboard and you are wanting to wire a new stereo in your dash and the current harness that is in the car is not fitting the radio correctly and you want or need it replaced. If this is the case you can contact a person who installs stereos and find out how much they will charge you for the installation.
If you are not adding a new stereo to the car then you are looking for the complete kit for your wiring harness to change out all the wiring in the dashboard of your car. In this case, a complete kit will run you around 525 dollars plus shipping if you order this online. Installation of this kit should take a person around 6 to 7 hours depending on how often they do this or not. I would take the car to a good mechanic to have this one done. if not you can try to use a company that installs stereos in a car because they are familiar with the wiring under the dashboard of your car. Depending on how much the company charges by the hour and I am going with 100 dollars an hour because that is what people charge here it should run you around 400-600 dollars plus the cost of the harness. In total, you are looking at around 1100-1300 dollars to change this out.
