      so my 05 impala is acting weird. heat wont come on when warming up, even if I let it warm up for 30 minutes or more as I tested it. once I start driving it would come on fine now it won’t come on at all and the temp gauge is all over place. will go from hot coolant temp

        I would suspect a sticking thermostat. For testing purpose you can remove and drive it to see how the temperature gauge functions. It may go up a little bit but most likely won’t reach the normal operating temperature. Also, this procedure is just for tesing, when you remove the thermostat you may notice that your idle is higher than normal. You can ignore that.
