jgc over heating with a/c on

the fans shold go on when the a/c starts i'm sending a diagram of wher ethe relays are. what is a pwm relay?

The pulse width modulated (PWM) radiator cooling fan relay is located behind the front bumper fascia below the right headlamp.

Which engine do you have?

i have a 2004 jgcl with a 4.0L, the pwm cooling fan relay is not located behind the headlight , i dropped the front bumper cover, pulled out the r side headlight and located the drilled holes where it has been said to be but it is not there.could it be that on this model year that the high and low fan relays in the fuse box on the r side under the hood next to the battery performs the function of the pwm relay.

My pal just had similar issues

I "BELIEVE" his is a 2000

The relay was (I think) Passenger side, under the headlight--and under a "Pain in the Butt to remove plastic cover"

With the battery removed, he said you could sorta "peek" at the relay

He told me the EZist thing for them (him and another feller) to do was they removed the headlight.

With a pencil type soldering iron they sorta "MELTED-CUT" a "Square" out of the Pain in the Butt Plastic Cover, under the where the headlight was, and directly above the relay.

He said it was really EZ then! They replaced the relay. Then they silicon-ed the plastic square back in that they melted out....He said fixin' the cover was really unnecessary, as it really served no purpose, other than as a cover, but they did it anyway.

.....Or you can take it all apart to get to it!

(I like the EZ way)

I got you a diagram--see left side

Let us know how it goes
