“My fuel gauge on my 2006 chevy trailblazer slowly stopped to where it is no longer working at all. Also, suddenly today, both of my dim (low beam) head lights stopped working after having the battery replaced. Have checked fuses and they are ok. I have seen many complaints for both of these issues.”
NHTSA complaint #10369408, filed 2010-12, 78,000 miles“My low beam headlights went out which shows it's a relay bad online it shows that there was a recall but in the database it doesn't show up for my vehicle”
NHTSA complaint #10854396, filed 2016-04, 1 miles“The air conditioning on my 2006 chevy Trailblazer Ext stopped working. The problem was the blower motor resistor module and resistor module connector. The parts had melted together, causing the wires to become loose at the connection. Apparently this is a common problem with my chevy model. There are many online postings indicating that the problem could cause a fire. Chevrolet company refused to even look at my vehicle until I paid a $110.00 diagnostic fee. The service technician immediately knew what the problem was and explained that it was a common problem with my model and the tahoe. …”
