What relay ? where is it located ? Front right radiator support ,behind right headlamp ? An just so you know your vehicle has two fans , one you can see behind the radiator an the other you can't see . It's located in front of the radiator . One pusher an the other pulls ! The PCM - engine computer energizes the relays turning on the fans > The coolant sensor is an input to the PCM an when engine temp. reaches 212 degrees the PCM turns on the fans . If you had a factory scan tool you could see if PCM can control the fans , energizing the relays ! Go to free wiring diagrams ! Do you know what a wiring diagram is .

My 2009 Compass won't start/crank; no communication with PCM but scanner will communicate with TCM and ABS module

Double check the fuses (Inside the car and on engine bay), there is a fuse for the OBDII linkageand sometimes it works together with other systems (Power Outlets, Stereo, Switch, etc). A bad PCM would also cause that but is not very likely.

I'm working on a 97' Oldsmobile Siloutte. I thought that I was having an issue with the fuel pump so I changed it. However, it turns out that the old fuel pump wasn't defective. It's...

The PCM does not supply the voltage to the fuel pump . All the PCM does is energize the fuel pump relay ,closing contacts in side the relay which connects the fuel pump with a B+ voltage supply from Fuel pump fuse 15amp location , under hood fuse box . You have a high resistance problem in the wiring to the fuel pump . bad connection , corrosion etc... Mastering Voltage Drop Testing with Pete Meier and Jerry Truglia

Cant find computer on my 2000 galant 2.4l motor

Hi there,

On earlier models, the ECM (also known as PCM & ECU) was located above the passenger side 'kick panel', hidden behind the glovebox.

However, on later models, Mitsubishi mounted the computer in behind the Centre Console (below and behind the ashtray area). You'll need to remove both centre console side panels.

The one you want, has a part number starting with: MR *****


Note: NEVER replace the PCM, unless your diagnostic codes codes confirm the PCM is faulty. Have your diagnostic codes read before disconnecting.

I need to know where the voltage regulator is located on my 1986 chrysler lasr 2.2 l turbo

It's actually controlled by two modules. Mainly the PCM but the Logic module located behind the right kick panel also plays a part in it. The first place to look for a problem though is the wiring going to the PCM.
