A/C problems.

[Mel9267]

Question, we have a 1999 Mercury Mountaineer (same as Explorer) that
has the EATC control system that just quit working. We replaced the control
module but it still doesn't work. We have checked all fuses and they are fine
but it appears that the module is getting no power. Does any one have any idea of what the problem could be?
Thanks

Welcome to this forum! I've moved your thread into the A/C & heater section. Did you check the fuses & relays? Is there a sufficient charge of freon in the system? Did you check the low pressure cycling switch?

Yes, per my original note, we have checked all of the fuses. I could not find a diagram to show the relays. The freon is fully charged and the low pressure cycling switch was
replaced. any other ideas?
Thanks

There are 2 fuse boxes. The high current fuse box under the hood has relays.
