My Acura RSX 2002 AC blows very hot at low speeds or rpms. At highway speed AC runs ok. Climate contriol diagnostic showed no codes. Car is running normal temperature.

left front wheel speed sensor is more then likely due, to a malfunction sensor for the abs sensor, badly connected sensor, or wiring, or contacts corroded or damaged, the knock sensor is usualy do to a fault sensor at the crank shaft where the timing belt is due, this is also more then likely to your engine turnover problems and is just coincidence when refueiling

The most common symptom of a failed thermostat is overheating at highway speeds. Your engine may be able to stay cool at low speeds because it's not working that hard, be sure coolant is ok! Good-day! the thermostat is sticking thats what it sounds like to me. its not opening properly.

Test both the cooling fan relay and the fuse (located under the hood and inside the control module box).

For the inop blower fan, test the switch if the fuse checks out.

sound like the trans is gettin hot, i would have a trans cooler installed

your ac compressor is freezing up try not putting it on cold all the way. put thermostat towards the red jus a lil but still on the cold side to see if that helps

The same thing happended to my Acura RSX and now they are saying that it is an electrical problem. I put new bulbs and both of them are fused

Most likely it will be the blower. Check to see if there is power to it, and then ground it. If it runs, the blower speed control is likely bad. If not it will be the blower motor.

BlowerMotor Relay is Located On Driver Side in Engine Compartment and is the LARGE Relay in center of box CLOSEST to you If you are Standing On the Driver side of Car This is A Culpret, Also the "BLOWER MOTOR RESISTOR" also can Cause What You describe.

Blower Unit Components Replacement

Note these items when overhauling the blower unit:


The recirculation control motor, the power transistor ), the blower motor (C), and the dust and pollen filters (D) can be replaced without removing the blower unit.

• Before reassembly, make sure that the recirculation control linkage and doors move smoothly.
• After reassembly, make sure the recirculation control motor runs smoothly.

Regarding the heating issue, sounds like your thermostat is stuck open so the coolant isn't heating up. (May need replacement) Does your engine temp guage show it running colder than normal?

either your ac condenser went out or your chem? needs to be recarged.
