My 2009 Jeep Liberty's blower works but I get no heat. The heat worked last week but all of the sudden with temps in the 20s it's blowing cold air. any Ideas?
make sure your fluid level is full. if it is you may have a bad thermostat.
It's your temp control under the radio. Take the face plate off, and check if your plugs have vibrated loose. Is it a auto temp system, or a regular? It sounds like the temp control is not opening up your valve to let hot antifreeze into your heater core. Hope this helps
A bit of a curveball here. the reservoir was full but the radiator wasn't. I filled the radiator and now have heat. so... how would the reservoir be full and the radiator so low it causes issues?
You may have a leak somewhere. Check for leaks under the car especially in the water pump area. It is also possible that you have a bad head gasket. That is less likely, but possible. If it keeps leaking and you can't find the source, there is a combustion leak test kit that you can buy at an auto parts store for about 40 bucks. There are good videos on you tube on how to perform it. If you don't want to tackle it, some shops have a sniffer that they can put in your exhaust while the engine is running.
iIf your liberty does not go over half on the temp gauge, then you don't have a overheating problem, your problem lies in the temp. control nobs. it's happen to me twice, with out any warning, don't go to the shop, and pay 100reds of you hard earned money, to get played around, with these shade tree mechanics.It's simple mechanics. no heat to the heater core, no heat!!!!!!!
I'm glad you found your radiator was low, u can't get heat, if theirs none going to the heater core!, but now what?, your losing antifreeze some where, no leaks on the ground?, then check to see if you have a lot of steam, whitish smoke coming from the exhaust, it could have a bad head or intake gasket, letting coolant into your fuel mixture????. hope this helps
you might have an air locked water pump, try taking out the allen head plug on top of the thermostat housing and fill with antifreeze
