the service "servie engine soon" warning light has come on in my 2004 mercury mountaineer. it is a V8 and has about 11700 miles on it. it is in good shape and I keep up on the maintenance. My local dealer has told me the "PCM" needs to be replaced and wants to charge me over $2100 to replace it. Is this reasonable? 2 Answers

I have a 2004 Mercury Mountaineer, V8, AWD, My problem, I think is in the computer? When I shut the engine off and try yo exit and lock the vehicle, setting the factory alarm system it won't do it. The digital display says that there is a "DOOR AJAR". I have checked all the doors as bet I can and they appear closed. BUT the interior lights remain on and the alarm will not set because off the ajar message. Am I missing something? Is the computer having a brain cramp.? I can get the alarm to set if I manually shut off the interior/dash lights too off. then it will work but no interior lights on the dash. This is driving me nuts. Can uou help?Thanks,John 12 Answers
