This 2003 Toyota 4Runner came in with the complaint that the a/c stops cooling after a while and the a/c lights on the dash start flashing. This is a common problem on later model Toyota’s in general. Most of the time it is just a failed compressor clutch relay but sometimes as in this case there is an updated part to correct the condition according to Toyota.
The MG CLT relay (magnetic clutch) is the white one in the center of the following picture.
The new relay I installed is black in color and it is and aftermarket design. I have used quite a few of these and have had no problems as of this post. There is a big difference in the cost of the original Toyota part and the aftermarket version.
The fuse box cover is marked MG CLT for the magnetic clutch relay. A quick test drive to confirm the problem was resolved and this one was done.
It is common enough that it should be available at most parts stores or a Toyota dealership. Standard Motor Products #RY465, Four Seasons #35874 or Airtex #1R1696
