if it is loosing coolant and smells like such in cab it is likely that the heater box or hoses has a leak easy to find with a coolant pressure test. if it fails it can be temp bypassed by joining the in and out hose that goes thru the fire wall. either that or your air con may have a blocked moisture pipe this will generally leak on floor when cornering and ac is on .. the fix is easy if you have access to a dust gun and in short bursts blow rubber pipe where condensation from air usually escapes out onto the road from . also recommended change the pollen filter in the cab it is in the ac system to purify the air and when it gets blocked that can cause this problem as well.

Heating fan switch not working

cab heater? there are 3 fans, engine,cab heat and A/C. so....
a stuck CAB switch is a bad switch. easy huh?
if the switch only works on high but does move, that is a bad heater fan Resistor block. (usually bolted to fan hosing as it is air cooled this part)

Change heater core water pump one pipe get hot

try some comma's?
my wild guess, is you are trying to fix a dead cab heater, right?
and if so, can be caused by 5 things wrong. total.
1 engine coolant not hot (180F or more)
2; fan dead.(cab heater fan)
3:or core , coolant path blocked. (seems you)
4; core exterior core blocked with leaves or pin needles. (sucked in)
5: optional core valve , stuck closed. (cable bad, etc)\

one pipe hot , means ,? core pipe 1 is hot, and other is dead cold?
this flow blockage , bingo !

if pipe 1 is 180F and other is 120f this is normal the heater is heating air in the cab and is dropping due to this heat exchange. (normal)
so why not do the 2 year full flush service now. (skipped i bet)
core hoses:
remove the 2 hoses on engine side, never core side (easy damage)
then back flush both hoses. with a garden hose.
if there is a valve there, test it and make sure it's opening... and free flowing.
and that both engine water ports are open too, from heater hose
to engine. (yes, they pack up too)

2005 Mitsubishi galant heat doesn't work. Blower works and air conditioning work but no heat comes out. Coolant is full. Just feels like outside air temp with heat on hot.

Your thermostat may be stuck open and your coolant isn't getting hot to warm the cab.Here's a link on how to replace,very easy to do.Don't let your pets near spilt coolant,will kill them.

Truck is overheating but no hot air in heater and full of antifreeze

It's easy to flush your heater core. I use a garden hose. My same truck as yours, lost heat in the cab. I used the garden hose trick, and flushed the problem away. It's as easy as removing both heater hoses from the heater core, and using an old garden hose that I cut the end off. Luckily, it slipped right onto the heater core inlet. Hooked the garden hose to the water spigot and turned it on. Let it run for a couple minutes. The plug should wash away.

2004 Chevy Silverado heater blows cold air. What would cause this problem?

the heat is independant from your ac. look for leaky radiator hoses or heater hoses,radiator cap,coolant

leaks inside your cab under the dashboard on your floor board. if you have non of these problems.

you may have a blocked or stopped up heater core and it will need to be replaced. depending on the

truck some replacements are easy and some hard , trucks and cars vary. good luck!

2004 Town Car, problem water under front floor mats, primarily on pasenger side. Have tried the solution to have heater discharge cleared by blowing with air pressure. Not the solution. Can you help???...

More than likely your heater core is gone bad and is leaking.They are usually buried deep in the passenger side dash.Usually not an easy fix.If you are not very car saavy, suggest you go to a repair shop.Hope this helps,good luck.

Heater stoped workin and blows cold air, how do ya fix it


The a/c and heating systems on cars today are pretty complex. 10 years ago replacing the thermostat usually did the trick, but today there are electric motors that operate the "blend doors" inside the dash…directing air flow from the heater core and A/C evaporator core to the cab of the vehicle. Always start by checking the actual coolant level inside the radiator itself to make sure it is full.

Then feel the upper and lower radiator hoses to see if they are hot (when the engine has been running awhile and has reached normal operating temperature), then feel the two heater hoses leading into the cab of the vehicle to see if they are both hot as well.

If you feel a drastic difference in one of the radiator hoses, I would try replacing the thermostat and see what happens. If all the heater and radiator hoses are pretty much the same temperature I would suspect there to be a control problem in the dash controls or in the blend door operation and a visit to you dealer or a qualified mechanic is my recommendation.

No heat in the cab. Replaced thermostat but that didnt fix the problem. Inlet hose to the heater core is hot but the outlet hose is barely warm when the engine is at operating temp. Clooged core?


You definitely have a clogged heater core, unfortunately those things get clogged with sediment and it is better to replace them then to clean them out. Since you have a truck the core should be easy to access. In most cars you have to remove the whole dash. I would recommend replacement as opposed to cleaning or flushing, as most sediment that builds up in the heater core is the inner coating of the core itself which has worn away due to multiple heating cycles.
