Hello, I have a 2004 Mercury Marauder which I bought new. I'm in north Alabama. Paul Casey, RIP, talked me into buying it back when life was good. After driving his, like I stole it, I was sold. I bought mine over the phone, sight unseen.
I am another on the list for EATC/air conditioning issues. Four years ago I did the O-ring fix and all was wonderful again after that...till now, I am bewildered...I have done the O-ring fix again...as the air was blowing out the defrost and the floor. However, that did not fix my problem. I ran the self diagnostics and had no fault codes.
I checked the system for vacuum leaks, there are none. I have 20 inches of vacuum at the EATC.
I am confused and confounded. I can operate the electronics, such as the AC compressor, the blend door (Changing from hot to cold or cold to hot, the air is cold. The heat is hot.), the fan speed, via the EATC, and MANUALLY jump the vacuum hose (I use a couple barb fitting and short piece of hose on the vacuum connector that goes to the EATC) to operate all the different vacuum actuators and they all work fine when I do this MANUALLY. I can make the AC blow out the DASH vents MANUALLY like they should do AUTOMATICALLY. It will not work with the vacuumm connector hooked to the EATC
I have now replaced the complete EATC TWICE, did not phase the problem of making the air blow out the dash vents (Which it still doesn't) ... still blowing out the defrost and floor. I have replaced the blower motor controller out under the hood mounted in the blower box ... just because I could...and then replaced that part again...because the first replacement made the blower quit working. I have taken the airbag out of the dash to check the blend door...it works fine...smooth and quiet...not gonna go there since I don't have to... After taking out the air bag and vent to the passenger far side, the EATC gave me a fault code of 025 and 052. I did not get any codes till I took out the air bag and vent duct ... I figured I upset the system with the effort it took to get the vent plastic extension out, which was a lot. I reran the EATC self diagnostics and cleared the codes. Blend door still works smoothly and quietly. Codes did not, have not reappeared. I took out the inside temperature sensor and disconnected the large white hose and blew it out...to clear any possible obstructions in the ac blower box. I reinstalled the temp sensor, still no cure.
I took the apron which covers the windshield wiper mechanism and cleaned out all the leaves and silt, because I could...made no difference. Cleaned out the blower box from the access on the firewall too. Made no difference.
What am I missing? Anyone got the solution? Any more parts I can replace?
