1988 jeep wrangler no heat

Hi
I just noticed this morning that my jeep wasn't getting up to normal temp and the heat was blowing cold air. It usually only takes around 5-10 min to warm up but the whole ride to work it stayed cold and the temp gauge did not move (40min ride to work). I checked the antifreeze and it was full in the radiator and im not really sure where to go from there. Any ideas?
Christian

If burping the system doesn't work, put a new thermostat in it

I would guess the thermostat went bad.

I burped the system and squeezed the hose coming off the top of the radiator a few times and it heated up like normal but when I stopped and turned it off for a few minutes it stopped working agian. Could the thermostat start working again and just stop? I'm going to pick one up tomorrow anyway to see if it helps.

I had the same issue about a year ago and it turned out to be a thermostat. Other possibilities could be blockage in your heater core or vent control issues.

They can get stuck. And for $4.00 its an easy and cheap thing to replace.

Cheers
