Where is the AC compressor relay located?
Where is the AC compressor relay located?
Locate the Relay In most cases, the relay is mounted on the fender well or fire wall. The relay in a typical A/C control installation has a three-wire connection. One wire is a ground, one wire is the input from the interior control panel and switches, and one wire is the power feed to the A/C compressor clutch.
What happens if the AC compressor relay goes out?
Without this relay, the AC compressor will not have power and the AC system will not function. The AC compressor relay is no different then other electrical relays – its electrical contacts will eventually wear or burn out, and the relay must be replaced.
How can I tell if my AC relay has a problem?
AC compressor is not turning on. One of the most obvious signs that the AC relay may have a problem is that the compressor is not coming on at all. In most cases, when the AC is turned on you will be able to hear the compressor switch on.
What’s the average rating of an AC compressor relay?
Average rating from 13 customers who received a AC Compressor Relay Replacement. Almost every single electrical system on a car is powered through some kind of switch or electrical relay, and the AC system and compressor are no exception. The AC compressor relay is responsible for supplying power to the AC compressor and clutch.
Is there a fuse or relay for the compressor clutch?
There is no fuse or relay for the compressor clutch. Power for the compressor clutch comes from one of the TIPM circuit boards, through connector C1, pin 50. However, the A/C control panel, among other things, gets power from fuse M34. That may be related. Check for power at the connector on the compressor clutch.

What to do if your a / C compressor won’t engage?
HOWEVER, if you cannot turn the compressor on, you cannot recharge your AC levels (grrrr). So you need to use a paper clip to bypass the relay switch and force the clutch to engage. You can then recharge the freon and re install the relay switch and it will sense more pressure and the clutch will engage by itself. Loading…
Why is my air conditioner compressor cycling on and off?
The air conditioner compressor was rapidly cycling on and off. I turned the A/C off and stopped putting R-134a into it becuase the compressor cycling was almost causing the car to die from the load it was putting on the engine. Onto Google I went.
What to do if your dash air conditioner is not working?
Check the comressor to see if the clutch is engaging, if not, or it is going on and off quickly, check the freon level first. There is a low pressure sensor that will no let the clutch engage if the freon pressure is low. This is words of wisdom passed down by my father who had 30 years in the automotive industry.
