TheHaze Posted November 25, 2008 Report Share Posted November 25, 2008 '99 Jeep Wrangler The heater works when it's warm out, but when it's cold it doesn't blow warm air at all, just cold. Engine temps are fine and has correct coolant level. Help! Quote Link to comment Share on other sites More sharing options...
Guest Removed Posted November 25, 2008 Report Share Posted November 25, 2008 do you have hot on both heater hose going to it? does it change from cold to colder when going from hot to cold...either blend door motor has failed(bottom of heater case on thepassenger side) or the heater core is pluged up...either way i could fix that for you... heater core sucks cause the whole dash has to be removed...i just did kbonds99 sons car, and doing a newer blazer at the moment...

It isn't colder than a/c, but rather luke-warmish. Quote Link to comment Share on other sites More sharing options...

Dave1647545494 Posted November 25, 2008 Report Share Posted November 25, 2008 your thinkimg cherokee the wranglers are still pretty basic take the heater hoses loose at the firewall and use a hose to flush through the core both ways see if any crud comes out of it then try the heat again Quote Link to comment Share on other sites More sharing options...
Smokey Posted November 25, 2008 Report Share Posted November 25, 2008 ^^^Try flushing it before you go ripping the dash out. I just did it in my Dakota with 225K miles and had chunks of mud come out of the damn thing! It makes GREAT heat now! I had the most success with "back flushing" it. I flushed it against the normal coolant flow to get any blockages out which worked wonders. Quote Link to comment Share on other sites More sharing options...
