It sounds like you need to service your cooling system. The cooling system may need to be flushed out due to dirty from corrosion. A sign of no heat in the heater and the engine is hot is low on antifreeze in the system. Check the antifreeze level first and add water just to get around to buy the things you need to service the cooling system. Buy antifreeze and a thermostat, drain the old antifreeze and replace the thermostat. Add new antifreeze with a 50/50 mix solution water/antifreeze. Too much antifreeze will gel and the cooling system will still run hot and to much water will boil over. Good luck. Keep me posted be glad to help.

Car running hot when idle


The most common reason for running hot at idle is the radiator fan is not running or pulling enough air thru the radiator. If you have a fan for the engine and one for the ac, the engine fan may not be working.
The radiator fan should come on when the coolant reaches 220 degrees. The computer sends a signal to the fan relay.

A/c blows hot air when the car is not moving but it will blow cold air when the car is moving.


Check to see if your electric cooling fan is working when the vehicle is in park with the engine and a/c running. If the fan isn't running then the a/c won't be able to blow cool air as it can't get rid of the heat through the condensor which is located ahead of the radiator. When you are driving over about 35 mph there is enough air being forced through the condensor and radiator to get rid of the heat and the a/c will start cooling properly again. If the fan isn't running and you sit with the car idling long enough [such as in heavy traffic] then the engine may overheat as it also has no way of cooling if the fan isn't working. Usually this fan is powerd by a 30 amp Maxi fuse but each model is a bit different. Your owners manual should have an illistration of the fuses and what they power. Good luck, hope this helps a bit!

Cooling fan 98 cavalier inop


This system is controlled my the power control module. when you need it the system sets a ground to the system
you can run a ground to the blower motor and it should come on. but you will need to put some kind of switch on it to cut it off so it will not kill your battery or just replace the module.

I HAVE A 98 CHEVY CAVALIER AND THE A/C BLOWS OUT


Hello,


If your Cavalier is equipped with an automatic climate control, the fault is possibly due to a defective indoor temperature sensor or a faulty temperatur regulating flap servo motor.

If it is a manual controlled A/C, the problem will be due to a defective expansion valve.

98 camaro,radiator fans not working only off and on when I turn on my air conditionor. Replaced temp control senser,relays,thermostat. what next PLEASE HELP!


Although rare, it is possible that the fan motor is bad. I don't know if the connectors are the same or if there is only one connector for the fans. My point is try to switch the connectors and turn the a/c on. One fan runs off the coolant temperature sensor and the other off the a/c hen the compressor is running. It basically senses a load on the engine and engages the fan. The one that works has power to it so you know if it does not run the other fan, the problem is the fan. If you have the V6, it may just not be getting hot enough for the fan to kick on. If you have the 5.7L, I would definitely confirm the fan is good because those engines are designed to run hot and they get up to running temperature very quick. Please rate me on this answer.

I have a 98 chevy cavalier and when i turn it on my engine fan spins but then stops.. but i have seen other car when they started the engine their fan keep up spining. why does my car does that?


is your car overheating???the fan isnt suppose to run when started(unless engine is hot), it may turn on then shut off. See if it runs when the vehicle gets hot and the A/C is on. Those engines with fans that move all the the time are belt driven. This is why they spin continually.

Overheating problems.


Two things come to mind: 1) The electric fans are working intermittently, and somehow stop receiving electricity at high engine speeds. With the car stopped, in park, wait till the fans come on, and have somebody else race the engine while you observe the fans to see if they stop. 2) Happened to me once that a mechanic reversed the polarity of the fans, so they would run backwards. At idle it is no problem, the fan just pushes the air outwards, toward the bumper, but at high speed, the fan air cancelled the oncoming fresh air, and the car would overheat instantly.

1994 CHEVY CAVALIER V-6 STARTS TO OVERHEAT WHEN A/C RUNNING. ALREADY CHANGED THERMOSTAT AND ADDED COOLANT, STILL RUNS HOT, SOUNDS LIKE THE COOLING FANS AREN'T COMING ON WHEN THEY ARE SUPPOSE TO. CONSTANT...


Make sure you get the air out. There may be "high spots" on the engine that you can unscrew to let the air pockets t. Close this small valve when just hot water comes out.
Unplug the radiator fan and use jumper leads to test the fan operation. Use a scan tool to check for codes. If you get a scan tool that gives live data, see that the PCM sees the actual temperature of the engine after 5 to 10 minutes of running. It should see the temp. rising to 225 degrees farenheit.
Replace engine temperature sensor if the PCM doesn't recognize the proper temperature. You ARE going to compare this to the temperature gauge!!!
If all else fails, get the PCM recalibrated or flashed at the dealership.
