Question about 1999 Chevrolet Blazer

1 Answer

My 98 S10 BLAZER'S heat does not work.

The coolant level is good. The engine runs at a normal operating temp. The blower runs at all speeds. Zero heat. I suspect the actuator valve but I'm not sure where its' at.

The most common reason for no heat is a faulty thermostat. this is an easy and cheap fix also. go to an autozone store and they will assist you in changing it.

No heat in my 1985 s10


Does the engine reach normal operating temp? With the engine warmed up, are the heater hoses, hot? Does the blower motor work? If all the above are ok, then you have to check temp door under the dash.

Tip

Over heating


Cold engine - - check that coolant level is correct - Ignition on but engine not running - set heter temp settings to max - set fan manual to one of the lower speeds - start engine and within 30 seconds rev it 3-4 times up to 3000rpm - shut off engine before end of 30 seconds (before it starts to heat) - reset climate to normal settings - recheck coolant and top up if necessary. Hot engine. - take car for a run to get up to operating temp - using caution - slowly open the bleed valve (steam and bubbles may come out) - close as soon as you see liquid coolant without excessive bubbles. - do not overtighten this as they are plastic threads. Just snug till it seals fully. - after engine cools check the coolant level again and top up if necessary. Check coolant level every few days for a few weeks and top up again if required - repeat the Hot engine bleed process again. If coolant keeps droping after 2-3 top ups have the system pressure tested. If you are still getting over temps have it analysed by a dealer. The temp is controlled by the engine computer so there may be another fault.

2006 chevy silverado 2500hd truck heats up to operating temp while in parking lot blower works well but truck will not blow any hot air until truck is driving at at least 15 to 20 mph. fuses good think...


If I understand you correctly, your temp gauge shows correct operating temperature, your blower fan blows air that you can feel with your hand from the right floor or dash outlet, but that air doesn't feel warm until you are moving?

If so, several possibilities come to mind. One is that your coolant level is low. Even though your temp gauge reads in the right range, the coolant level could be low enough that it doesn't reach the heater core until there is enough engine RPM to create more pressure from the water pump and force what coolant is there toward the heater core. Another possibility is that your heater controls are not able to do their job. A stuck flapper in the duct or a malfunction with the temperature control system could be causing the problem, and at 15-20 MPH there is enough air coming through the outside air vents to provide some heat.

I'd check the coolant level first, though. The other possibilities are more far-fetched.

Why my heater in 2000 plymouth breeze only gives a little heat? Could it be a hose ? I know it's not the thermostat,the blowers ar working. I am wonding if theres some hoses that could be leaking?I don't...


it could be the cold air blend door or the thermostat is the engine temp up to the middle of the gauge or close to it if so then thermostat is ok if not then go ahead and replace it.

Warm heat not hot


Check antifreeze level, if it is low coolant may not flow through heater core. If coolant level is ok feel the heater hose with engine running at normal operating temp and heat on high, if one hose is much cooler than the other you have a bad heat control valve or a pluged heater core.

No heat in car and temp gauge rises while driving but stays half


With engine cold, remove rad cap & check level in rad. Top it up if needed to 1 or 2 inches from top. Start engine, turn heater on (not defrost) and observe coolant level as engine warms up, add if necessary. Radiator fan should be off, and only come on when engine reaches normal operating temperature, for a short time, then shut off again. Let it run until that happens about 3 times, then put rad cap back on. If temperature gauge climbs up over normal toward hot, too much, shut it off. Do you now have heat? Is rad fan acting as I described? Let me know.

I have no heat in my 2000 expedition. Is it the heating coil? Or could there be another problem?


Is the blower fan for the heater going on, but only cold air? If the fan is working, but no hot air situation, 1st check the coolant level, if it's low, the coolant won't flow thru the heater core, so little or no heat. If level is ok, what does the engine temp gauge indicate? Is the engine running normal temp range, cold, hot? Let me know answers to these questions so I can help u.

94 bmw 318iC Heater not working


1st thing to check is the coolant level. Low coolant level results in no, or little heat (not enough coolant to circulate thru the heater core). What does your engine temp gauge indicate? (or is it just a warning light?) If the car is running at what appears to be lower than normal temp., u may have a thermostat that's stuck open. This would cause the engine to not reach operating temp, and u would not have heat. Check the above 2 items 1st, then let me know what u found. If that doesn't fix it, we will continue, let's do the easy and not too expensive stuff 1st!
