Jomorisn Posted April 14, 2023 Share Posted April 14, 2023 The A/C used to work fine in this truck but something hap[peded lately, When my air conditioner is on the fan on the engine doesn't engage and compressor short cycles if I unplug the wire to the left of the radiator the fan engages and it stays engaged and the compressor seems to run longer with the fan engaged. Is there clutch fan is there a relay that controlls the engine fan? Also is there a relay next to the APAD? Thanks in advance for any and all help Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted April 15, 2023 Share Posted April 15, 2023 Has the A/C system been recharged recently? Check the condition of the binary switch in the reciever dryer bottle, as well as the wires. Does the APADS show any codes? The wire on the radiator??? is it connected to a fan control valve? a brass valve about 5/8'' diameter, and 3'' long?

fjh Posted April 15, 2023 Share Posted April 15, 2023 If It is short cycling I would have the charge checked! Just sayin! 1 Quote Link to comment Share on other sites More sharing options...
