Does the fan kick on when you turn the a/c on?
Over heating only with AC on

Does the fan run on HIGH SPEED when the AC is on??

Took the car to my mechanic real quick to check the refrigerant. Pressure was suoer high. They vacuumed the system, and filled it again. No leaks also. I will drive it and test it now. Mechanic did say that the none clicking is not normal and compressor will take a crap sooner then later. Anyways, received the condenser today. All other parts getting to me by friday the latest.

Yes sir. I can feel the difference.

Did they replace the orfice tube and receiver drier also (I hope so, otherwise you need a new mechanic).
Is the fan running on high speed with a/c on?

Orfice tube was replaced about 2 years ago with a new accumilator and ac line. I didnt bother asking him to check nor replace nothing as all these parts should be delivered today and I will start on replacing them. I just went by my mechanic to have the pressure checked and get frion. I have no leaks either. Ac is still not as cold. Cant wait for parts.

So i have a small update guys.
So i yet have not installed the new ac parts. So i started playing with my sct tune. Making few adjustments with my rpms. Being that i had steeda crank and water pump pulley installed, i had my idle rpm in park and drive bumped to 1000 at park and 900 in drive. This was done due to my loud after market car audio system. Switching to stock crank and water pump pulley, i had to lower my rpms. So i lowered it to 700 rpm in park and drive. Been driving this way for a few days. Ac still not doing good but car did not over heat. The highest it saw was 196 with a 96 degree weather. I understand that crown vics p71 have a higher idle due to all there electronics. I beleive its 800 in drive and 900 in park. So i went ahead and bumped up the rpms today just to test the boat. I honestly do the like feeling of the 900 and 800 rpms but car started to over heat. It made its way up to 208 with ac on. Of course, minute i shut off the ac, it started dropping which once again im dealing with a ac compressor overloading issue because it failing or my condensor is blocking air flow because the fins are shoot closed in certain spots.
Trying to find the time to install these parts already.

Can higher rpm really cause an overheating issue with cams?

No, unless the air flow for rad is restricted.

Ive been super busy. Still have to install the a/c compressor and condenser, I'm still trying to figure out if there can be anything esle wrong. Last thing I want is to install these parts and have the same issue going on.
Looking at all Ive done to car after the engine build, I believe I never mentioned the AUX B&M trans cooler I have installed in line with the factory trans cooler. Not sure to the where you guys that have installed an aux cooler would install it but, I installed mine right in front of the A/C condenser on the passenger side hanging off the rad support. wondering if this can be my issue now.
Can the aux cooler be getting really hot, throwing all that extra heat onto the ac condenser causing the fan to blow all that extra heat onto the engine making it over heat? Maybe the aux cooler is installed wrong?
I guess i have a few things to check
