If your reading is less than 2.0 ohms: This could indicate a short circuit in the coil, which would blow the compressor clutch coil fuse. A reading of 0.L indicates an opening in the clutch coil windings. This could indicate an open circuit in the coil, which would prevent any current from flowing and prevent the clutch from engaging.3 SPN 111/FMI 4 -EPA07 -EPAlO -GHG14 3 SPN 111/FMI 4 -EPA07 -EPA10 -GHG14 Coolant Level Circuit Failed Low Table 2.

This fault is telling you that the voltage on the HVAC compressor clutch is low. This can be caused by a rubbed through wire, a plug with corrosion in it, or the more common is the HVAC clutch on the compressor is going out. If you can get someone to look at that clutch, you will want to do it sooner than later.Circuit Description The air conditioner clutch solenoid is a device used by the electronic control module (ECM) to control the air conditioner by sending a All Categories All ProductsSPN 3512 FMI 14 - VREF 4 voltage above or below normal.

And found air conditioner started working.To power the clutch the body controller must see an input from the driver controls, thermistors must be 28 degree F or higher. Body controller must see some pressure in the system, (not sure how much) to allow the compressor to run. There really isn't anything you can do if you cannot monitor the body controller with Diamond Logic software.Bad AC compressor clutch symptoms include a lack of cooling and noise coming from the engine among others. To fix the issue, check the wiring, fuses, and ground before turning to the clutch itself. The cost of a replacement clutch ranges between $200 and $400. In this blog post, we will discuss 10 bad AC compressor clutch symptoms.

A damaged or seized A/C compressor can prevent the clutch from engaging. If the compressor is not spinning freely, it will be unable to engage the clutch. 6. Broken Drive Belt. The drive belt connects the A/C compressor pulley to the engine. If it breaks or becomes loose, the compressor won't turn, and the clutch won't engage.Power to the clutch is sent from the body controller. The body controller is monitoring for inputs from the driver controls, temperature thermistors and a/c high pressure switch. To power the clutch the body controller must see an input from the driver controls, thermistors must be 28 degree F or higher.

SPN 3512 FMI 14 - VREF 4 voltage above or below normal. Fault Overview. Fault code sets when Engine Control Module (ECM) detects that VREF 4 circuit voltage is greater than 5.1 volts or less than 4.9 volts. This is the only 3512 fault listed for that engine .One way to check the diode polarity is to use a meter on the ohms scale. Unplug the compressor clutch from the wiring. Put the meter on rx1 scale. Put the red lead to one wire and the black lead to the other. You should read a low ohm reading, or you should get a very high or no reading.That is a diode like you suspected. The temp cutout is screwed into back of compressor if it is fitted. Usually the diode is integrated into coil but can be external on replacement brands. on 97 and down the spike is taken by pressure cycling switch and fed back to a monitoring pin on ECM.April 26, 2023 by Robert Walker. It's a daunting feeling when you are left with an AC compressor running but no pressure change. This is a clear indication that something is not right in your car AC. This may stem from multiple culprits, such as a refrigerant leak, a faulty compressor, a fluid leak, an AC clutch, or a clogged expansion valve.That fault SA 25 spn 876 is for your compressor clutch. The clutch on your AC compressor has a return voltage too low. I recommend either replacing the clutch or the whole AC compressor. Sometimes the wire harness will cause the low voltage, but it is more common to have the clutch burn out behind the locking plate on those Cascadia trucks.91.1 SPN 2629/FMI 3 This condition is typically open circuit or short to power. 91.1.1 Open Circuit/Short to Power Check Check as follows: 1. Turn the ignition ON (key ON, engine OFF). 2. Check for multiple codes. [a] If codes 1636/3, 2629/3 and 412/3 are active at the same time, go to step 3. [b] If only fault 2629/3 is active, go to step 5. 3.

Pinpointing the specific type of noise your AC compressor makes when the clutch engages is crucial to diagnosing the issue: Squealing: This high-pitched noise often suggests a belt issue. The belt may be old and stretched, causing it to slip on the pulleys. It can also indicate misalignment or a lack of tension.The control head in the passenger area also has a switch that signals the desire for air conditioning. I think where that signal goes depends on model and style of HVAC. Check the two switches if you are determined that the clutch is not getting power. A reading of 40psi should be enough to engage the compressor clutch.These are the small actuators that control the fresh air, temp, and air direction.

Instagram:https://instagram. kronos scripps employee loginharbor freight locations in californianorthway accident this morningmcalister's deli prattville Poor grounding is the final reason behind an open circuit in the compressor clutch. The cable ground can be found near the compressor. Occasionally, it breaks due to corrosion buildup. This can interrupt the flow of electricity and decrease the magnetic power of the compressor clutch. 2. Poor Refrigerant Pressure SwitchInsert both ends of a wire into that plug. Turn on the engine and the AC. If it works then the switch is preventing the AC from operating, either due to pressure being out of bounds or the switch is faulty. If it doesn't then the clutch has an issue ranging from a broken wire to a failed clutch. 1011 riverside avengk dcpr6e cross reference The most common problems with the Kia Sorento include issues with the headlamps and the failure of the air conditioner compressor clutch.
