May 27, 2024 · Hello, I am trying to solve a problem with the low-speed cooling fan operation on a 2006 PT Cruiser base model with the 2.4L MFI DOHC 4 CYL VIN B engine with 5 speed manual transmission. When the air condition is active the low-speed fan will not operate. Within moments the air conditioner stops...

May 22, 2023 · On and earlier post ( see 2004 PT GT Turbo: Cooling fan or PCM?) I wrote about the issues I was having with codes that kept popping. Got busy with other things and came back to it and just now warming up the engine got another P0480 code. Turned off the engine and the fan proceded to run full blast.

Aug 12, 2019 · The fan needs to be able to keep the engine under all conditions. But because of emissions the engine needs a thermostat that keeps temps high. So once the thermostat opens, a high cooling fan speed is needed to keep from overheating. 2) But running a cooling fan on high all the time would present a large electrical draw which affects fuel economy.

Jun 25, 2014 · I have a 2007 PT and the ac cooling fan is not turning on even though the high side pressures go well over 300 psi. I am trying to diagnose the problem but the Mitchell manual shows a cooling fan module in front of the rad for 2007 but I have two relays on the back side of the fan shroud. If...

Feb 9, 2022 · Hi, my name is Greg from California. Greetings all! This is my first time here and I have a problem with my 2007 PT Cruiser 2.4 L non Turbo 4 door. Up until the other day the cooling fan worked with no problems. Then a gremlin sneaked in and now the cooling fan will not come on when the engine...

Jul 3, 2023 · Separate the 4 wire electricalal connector at fan shroud assembly. Connect jumper wire from battery positive terminal to pin #1, fan shroud assembly side of wiring. Connect jumper wire ito pin #2 and pin #4 at fan shroud assembly side of wiring connector in turn. You should hear and feel the relays click.

Sep 12, 2022 · It may have some air, instead of 100% refrigerant in the system. The A/C system is a closed system, if you had to add refrigerant, you have a leak. The leak must be found & fixed first & the cooling fan must work. The compressor can compress 'air', but the high side pressure can skyrocket (especially if the condenser/radiator fan isn't working).

Oct 6, 2018 · Somewhere between the battery and the plug for the cooling fan, +12V is disappearing into the ether. Fan and both relays are new, all fuses are good, with the key on I have 12V on fuse 12 under the dash and the 40 amp breaker under the hood, but nothing at the fan plug. This is with the A/C on...

Jun 27, 2021 · The air conditioning system is designed such that the radiator cooling fan will not engage until compressor discharge pressure reaches 280 - 320 psi. Depending upon ambient temperature and if the vehicle is in full sunlight it might take several minutes for the system to reach that pressure from initial start up. Is the A/C compressor engaging?

May 20, 2018 · The cooling fan issue was diagnosed as a inoperable low speed fan relay. It required the replacement of the entire fan assembly. Unfortunately, the car is out of the 3yr/36,000mi warranty so I had to eat the cost but at least it's fixed.
