So i bought a 94 camaro z28 m6 in the beginning of September after owning a 99 camaro 3.8l m5 for a year. i just started noticing a few problems with it. the first is my heat does not seem to be working. i thought it worked when i first got it but it wasn't very warm. it blows fine just isn't warm. i know for sure my ac doesn't work at all. im not sure if that has to do with it or not. i thought it might be the heater core went out but it doesn't smell or blow smoke. the second is my ip dimmer fuse keeps blowing. the fuse that controls the lights behind the gauges. i think it might be the dimmer switch going bad but not sure. the switch will dim the gauge lights but will only turn the interior light on every once in awhile. any input would be great since it is getting cold in Michigan and the heat would be nice. i don't plan on driving it once the snow hits but right now the windows are starting to fog.

 

what is your water temp like??

How long should be running before checking?

 

After driving it for 10-15 mins my temp is sitting at the half way mark.
