Hi all,

I'm new to this forum, and I'd like to inquire the whereabout of a headlight sensor for a 2008 grand marquis? I also would appreciate an answer for a faulty temprature gauge that is always at C mark for a 2000 grand marquis with 91,000 mls. The car isn't having any overheating prob but I'd like to see the needle work properly. Thank you in advance for your thoughtful answers!

 

You could try looking on top of the dash near the defroster for the headlight sensor. It should look like a little tinted eye. If not there, I'm not sure. As for the temp gauge always reading cold, you may need to replace the coolant temp sensor.

 

Thank you very much; I'll try your suggestion.
