SOURCE: Olds silhouette heater blows cold air

as long as the engine temperature is normal, i would suspect a clogged heater core, the dex-cool antifreeze is notorious for building up deposits in cooling system. have heater core flushed first to see if it makes any difference

SOURCE: 1998 Oldsmobile Intrigue-no heater or a/c fan blowing

either your blower motor is bad or your switch is. You can run a jumper to the motor and see if it kicks in. If that works then run a jumber from your switch to your motor and see if that works. Both are easily replaced, and don't take long.

Truck doesn't heat while idling


Could be low on antifreeze. The heater core is the highest spot in the cooling system and it may develop an air pocket. Another possibility is the thermostat is stuck partially open and doesn't let the engine warm correctly, watch your temp gauge on the dash and see if it comes up to the middle like it should while idling. If it doesn't, it may need replacement.

Most likely it is a clogged heater core. Have your heater core reverse flushed or your blend door is stuck open.

No heat , replaced radiator , water pump, rad. cap , hoses and flushed system twice.blows cool air.whats left?


Thermostat.? if you haven't? Do it first then try it. While the car is running for a while touch the heater hoses that lead to the firewall. if one is cold and one is hot? You have a blocked Heater core. Follow the hoses back to the engine. Unconnect them both. By using a garden hose flush out the heater core do one side and then reverse by doing the other hose Lots of junk will come out so be care ful. Mistake people make is "Flushing the system" That doesn't mean your flushing the heater core.
Seeing that you have done everything else it could be the thermostat which you didn't list or the heater core being clogged. When you finished installing the thermostat and flushing the heater core out. Replenish the coolant system . If you have a bleeder on the thermostat housing? use it . loosen it and top off the fluid until you see fluid comeout of the bleeder. The system being air bound would cause no heat..

The heater still won't work after I changed the thermostat on my


Get a female garden hose adapter from the local hardware store. Disconnect the heater hose from behind the fan pulley and attach the hose connection. Disconnect the other heater hose behind the alternator, aim it towards the ground and flush water through the heater core. This worked on my truck.

The heat system is broken


Hi,

You haven't said what is actually wrong with the heat system (there can be several different failures). For the time being I'll assume the fan blows plenty of air but the air is always cool/cold regardless of where the heat temperature selector is positioned.

The most common cause on these cars is a plugged heater core. With the engine at normal operating temperature, feel the heater core hoses (under-hood, mid/lower portion of firewall, access from passengers side). They should both be very warm. If not expect blockage in the heater core.

While a replacement heater core along with a good cooling system flush is the ultimate cure, reverse flushing the heater core will restore heat. This can be accomplished with a garden hose. Disconnect both heater core hoses (not with the engine hot as the coolant get very hot!!) and connect a garden hose. Turn on the water supply to flush the core. Flush the core in both directions (by hooking the hose to one side of the heater core and letting the water run, then disconnecting and connecting to other side of the heater core...). An old garden hose with end cut will work fine if your existing hose will not fit over the pipe (plumb it together anyway you can).

The heater core sits rather low in the cooling system. This means crud in the system will settle there eventually causing blockage. If you flush the core the crud will eventually cause blockage again. Reflushing will work over and over again if saving money is the primary goal.

If this is not the problem, the blend air door is probably not working.

Reply and we'll continue. I don't want to repeat things that have already been done, as $2000 should of covered both things I have mentioned.
