Have 03 Honda Accord ex 6cyl. AC will blow cold for 20-30 minutes then the compressor stops. Have changed the thermister, low pressure cut out switch, and receiver drier. System has been recharged and pressures are good. Any suggestions? Contact: [email protected].
Thanks

Icing Up Situation?

If you notice, after driving the vehicle for a while, that air stops coming out of the vents, the A/C clutch cycling switch may be bad. The cycling switch is supposed to control the evaporator core pressure at a point where the plate/fin surface temperature will be maintained slightly above freezing. Instead, it may be energizing the clutch too much and the system is icing up. In this situation, simply unscrew the old cycling switch from the Schrader valve-type fitting on the accumulator, coat the threads and O-ring with PAG oil, and install the proper cycling switch. It is not necessary to discharge the refrigerant system to remove the switch. The cycling switch's cut-on and cut-off pressures are readily available in manuals; therefore, its operation can be monitored by the manifold gauge set and you can tell whether it's working properly or not.

On your Accord, the TXV may be bad and causing the situation described above.

Hey Tex, could it be his fan belt is too loose?

I doubt it.
