1997 Ford Taurus

Air Conditioning problem
1997 Ford Taurus 6 cyl Two Wheel Drive Automatic 114000 miles

I am trying to debug an A/C issue and need some input. 97 Taurus with 114000 miles. A/C has alway been stable until recently when compressor froze up. I replaced Accumulator, Compressor, Orifice, oil and freon. After recharge I noticed that Radiator Cooling fans did not immediately engage when A/C switch was turned on. I checked my 98 Taurus and Fans came on instantly.
Goes like this.
Turn on A/C, no fans. A/C begins cooling and pressure rises on high side, low side goes down as expected. High side continues to climb until 350 psi when compressor shuts off and the cooling fans come on. At about 100 psi COmpressor turns back on and fans are still on keeping pressure at 150 psi. Then fans turn off and pressure rises back to 350 psi where cycle strats all over again.
What I know. I think A/C high pressure switch is fine (replaced anyway) and A/C clutch switch is good. I am not sure about the CCRM (Constant Control Relay Module).
Assumption. I do beleive cooling fans should engage immediately when compressor turns on. SOme I am thing CCRM or fuse or?

Anyone know of any test I can run to help find out why fans do not come on with A/C switch?

Probably going to be looking at the CCRM conncetor, for burnt or bent or pushed out pins, and burnt wires...

You might want to click on the link in my sig file, there are 85 steps in diagnosing the fans, and CCRM and PCM...

Thanks Merlin2021 for responding. I am not sure of your suggestion to click on link in your sig for additional help becuase what I am directed to is some manuals that are for fee. Is this what you meant?
I have a Chilton's but is does not go into diags for CCRM and PCM. I did inspect CCRM and did not find any visible issues with wiring and pins. I do think it might be the PCM since relays are turning on fan when engine is hot, just not fans when the AC is tunred on.
? If else have any suggestion fell free to add your two cents.

First thing is make sure the ECT which is the engine coolant temp sensor is in range, then check this info out

CCRM (Constant Control Relay Module) was faulty and had to be replaced.
