Question type: Maintenance & Repair

'07 HHR the engine temp gauge only works some of the time - when not working the heater still works but not the A/C. If the engine temp gauge is working the A/C works. The engine light stays on for no apparent reason and the left rear passenger door lock no longer works with the rest of the door locks.

It was a damaged thermostat that was causing the engine light to come on and the temp gauge to not work. The rubber on the thermostat was all shot to hell, stretched out, torn and missing some pieces. After I replaced it the, temp gauge started working again and the engine light went out after I had driven about 24 miles.

I just bought my 2007 HHR 3 weeks ago and yesterday I noticed the exact same problem. When the temp gauge didn't work the a/c didn't work either and the engine light came on and has stayed on since. About every 3rd trip the A/C and temp gauge will work. You mentioned that you replaced the thermostat and it fixed the temp gauge problem but what about the a/c? Thanks.

This is an easy fix. Just did it myself in my driveway. It will take you longer to remove and re-install the lower radiator hose than it will to replace the thermostat. My advice would be to go to Autozone and spend $37.00 on an OEM hose clamp tool, and make sure you have an extra long extension for your ratchet, and of course, a 10 mm socket. The thermostat housing itself does not require a gasket, the thermostat itself has an o-ring on it, so don't buy an extra gasket, it already comes installed on the new thermostat(22.99 at Autozone). I was shocked at how quick this was to do! Save your hard earned cash and do it yourself!!

After replacing the thermostat did it also fix the AC problem?
