Stuck thermostat maybe.

if the heater doesn’t work the antifreeze isn’t circulating. i would check to see if the thermostat is bad

[2StrongMNG]

A test would be to just take the thermostat out and run it for awhile right?

[joescorpio]

you could take the thermostat out and put it in some boiling water to see if it opens, just a thought

[Trcustoms719]

Yes you can test the thermostat in boiling water but, they are so cheap just put a new one in as maintenance
even if the old one opens in boiling water.

Start with the basics. Here’s some good vids.

a few years back i couldnt figure out why my car was over heating, the fan was working it wasnt leaking the thermostat was fine the fuses and relays apeared to be fine. so i rewired the fan to the acc mode on the igniton and whenever the car was in the on position the fan kept the radiator cool. not saying this is a good idea but it worked as a temporary fix.

I would avoid a temporary fix and start with the videos I posted to find a permanent solution to your problem. I personally would rather find the cause of the fans not working rather than wiring the circuit to my ignition switch. I agree it’s a crafty temporary fix, but I would rather just fix the issue.

check the coolant level. it needs to be full and free of air. make sure fans are operating.C8-)

Yep I did make videos on this subject that cover a lot of possible causes, I recommend following the steps in the videos to see if you can find the cause. BTW don’t say thermostat right off the bat, it’s actually about #3 or #4 on the list of causes in my opinion.
