Lincoln Repair Questions? Ask a Mechanic for Answers ASAP
The first code for the solar sensor, is common but not all that important to diagnose. The last code is for battery voltage low, also a common code that can occur at any time the battery voltage went less than 10 volts. I would stick with diagnosing the discharge temp sensor code. See the diag steps for both the first and 2nd codes below.
You want a excellent 5 star answer & I would like to be rated the same for providing it. Consider I don't know your skill level & I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies. Try your best to respond with good detail so I can do the same. I normally log in at 3pm and work late. A rating is required. Your rating me, what I type. I am not an employee of this website, nor have control over the fees or the time it took to get a response. If you rate negative or not at all you still paid, but I get nothing. I want you pleased with me and my efforts, so let me know if your experience here has come up short.
The sunload sensor is at the base of the windshield in the top of the dash accessed by gently popping up and off the top of the dash.
The RH air discharge air temp sensor is above the front passengers left foot near the left glove box hinge.
Sorry I do not have the part numbers. I have a Ford tech login, not a parts person login. If the battery is weak, worn out, and old then yes replacing it would be a good step. We see the battery voltage code so often, it normally results in no repair needed. No the glove box is not removed to get to the sensor.
Yes, any sensor faulty on the HVAC system can cause the compressor not to run.
The red light is the theft light. The bubble is the auto lamp sensor.
When you did the diag steps did the conclusion in those tests confirm the sensors were to blame, not the wiring nor module?
Accept the invite for extended service and I can attach more files for this new code.
Because I have reached my file upload limit. I have been paid nothing, you have to rate to do that.
Rating does not close the post. I have to follow the rules the website has for the techs that work here.
The original question you asked "01 Lincoln ls v8 throwing hvac codes 12-61 19-67 16-76" That is the only one I am allowed to address.
You now have new codes and concerns. So for me to be allowed to address those the original issue has to be rated and or extended service accepted.
If you do not want to compensate me, I can opt out and get you back on the waiting list.
Contact the website to do that. Thanks for letting me try to help you.
