Note that the cab fuse box has a fuse for the ac relay and the relay is in the under hood fuse box.

Sounds like the X contact relay. I would replace that. Sometimes called the Load Reduction Relay.

You diagnosis is wrong in my opinion, that module will not drain a good battery, first have the battery load tested (Autozone and others do the test for free), if it is good then look for some kind of light left on or staying on, suspects are visor vanity lights and glove box and console lights.

With the 2.4L....no relay... but found this....

check the freon there are high and low pressure swithes and will prevent a/c from workin
to protect compressor

It is going to be 134A (134). You also use 7.75 oz of PAG Oil for your ac compressor.

Good luck.

Look to see if the ac compressor is turning,look at the center of the pulley on the compressor,if it is turning,it could be a stopped up orifice tube,if it is not turning,check the freon,make sure you have not got a leak.

Fuses are in the kick panel on the passenger side. If it blows again, you will need to find the malfunction (don't put in a higher rated fuse) Most times the blower motor will cause fuse failure as when the motor gets older it begins to draw excessive amperage...but don't change it till it is actually verified as being bad.

First, check the fuses for the fan, AC and climate control. Could be just that simple. Otherwise, try swapping out relays with the same type by removing one from another device in your power box under the hood. Be sure you use the exact same numbered relay!

Sounds like a transmission cooler would help this problem. Also have the system backflushed.
