My car won't blow warm air?

Question

It was really cold this morning and when I tried to turn on the warm air it only blew out cold. What would cause this? Could it be the thermostat?

Answer 1

DID YOU WAIT FOR THE CAR TO WARM UP FIRST...

Answer 2

Here's the correct answer. (I am assuming you are waiting a sufficient amount of time for the engine to warm up, and you have checked your antifreeze level to see if the radiator is properly filled). If after a few minutes you still aren't getting any heat, then your thermostat is likely stuck in the open position. The only way to fix this is to replace the thermostat. Be sure to get a new gasket as well...most thermostats should come with a new one. If you are doing it yourself, take note of which end of the thermostat is facing towards the engine, and be sure to install the new one the same way. Also, don't overtighten the bolts when reinstalling...you can crack the housing.

Hope this info helped.

bypass to a aspects homestead, purchase a pocket thermometer and insert it into the sprint vent. turn the a/c to max or recirc mode, blower on hi and word what temperature is actual exiting the vents. If the air temp is 35 to 50 tiers then you definately are probably getting all you receives. that is available the nice and cozy water reduce off valve is malfunctioning and allowinghot water to run through the heater center which will over vome the a/c on warm days. that is likewise available the vac operated "blend" doorways at the instant are not operating awesome and also you want that corrected. I actually have given you the most difficulty-free issues to analyze out herein. BTW: 1999 GM and all different makes do not use freon, that is banned- because that 1993. you've refrigerant R134A. Your equipment isn't out of date, it isn't blowing through the refrigerant. the following is a crash route: The compressor pumps liquid R134A less than hi rigidity from the compressor to the condensor center the position it surrenders absorbed warmth. Them that is pumped less than hi rigidity through an accumulator or drier, then through an orifice or develop valve or some kind of restrictor into the evaporator center the position that is now a decrease rigidity gas the position it absorbs warmth from the cabin air. From there is flows less than low rigidity lower back to the compressor and recycles persistently till close down. See in case your motor vehicle has an interior air clear out, if certain ck or replace it, examine the temp on the vents as earlier defined herein, and be particular the belts at the instant are not slipping on the compressor. On fairly warm days lower back use max or recirc settings because it makes use of strictly interior air it quite is way less demanding to sit back than the clean outdoors air it quite is warm. there'll be a noticable vast difference interior of both settings on my own. BTW: the fats line is the low rigidity line the dmaller line the severe rigidity. in case you determine that you want a cost of refrigerant and absence the skills, you should properly be critically injured ot killed if improperly dealt with or executed. evaluate your ability stages and act for this reason, saving some money in demanding artwork isn't properly worth an eternal of deadly harm.

First check the radiator to be sure it is full. This happened to me once, where all of a sudden I lost my heat, and that was the problem.
Then check the thermostat.
Always do the cheapest easiest things first when working on a car.
Lots of luck

Answer 5

You probably still have your winter air in your tires and the winter oil in the engine. Stop down to the gas station and ask them to swap out your winter air and winter oil. That should solve the problem.

Answer 6

Try turning the air conditioner off!

Answer 7

it take time if it from a cold start the motor needs to warm up first, than the heater would work. try it midday if it works when you need to wait your oil need to lube the motor .

Could be...make sure you have oil and coolant- see if the floor on the passenger side is wet- could be a bad heater core.
