#904 of 915 Blower Problems-98 Lincoln Town Car by zmgoshert Nov 03, 2009 (3:20 pm)
Hi   I've been trouble-shooting problems I've been having with my blower motor and am at a loss. My air randomly will not start up and I can not figure out why. Listed below are what I have tested to far.   1. Blower Speed Control Module- Knowing that these were notorious for having bad solder problems in the '98's I checked here first. Once removed, the BSCM looked almost as if it were new. No problems aesthetically.   2. Voltages- the line into my blower motor is receiving 14 volts when on high, meaning that there doesn't appear to be any problems upstream (BSCM, wiring, etc.)   3. The Blower Motor- Once I removed it from it's housing I tried connecting it up and everything worked fine on it. There did not appear to be anything in the housing itself that may be obstructing it.   Where I am confused is that the blower seems to work just fine for a while, then all of a sudden won't want to turn on. It always happens once the engine has been turned off (won't ever quit in the middle of working). I have also noticed what seems like a metallic grinding sound that comes from the engine when I turn on the air at first. I thought it may be the compressor, but I checked it and it's not trying to kick on when I get the sound (the A/C was off also).   Does anyone have any ideas of what I should be looking at?

Replying to: zmgoshert (Nov 03, 2009 3:20 pm) I have a large fleet of Ford products (Mostly '97 to '03 E Series vans), and I own a 99 TC Cartier. Over time we have had blower motor problems with this fleet where the rotary switch would wear out (obviously not equipped with ATC), the connection plug at that switch would o/heat melt the plug end allowing the blade connector to expand from the heat and disconnect.With the molded plug end melted it could not hold the blade in contact with its mating part. Disconnection. BSCMs that have thin wire coils to produce the various speeds of the blower motor, can have that crimp between that thin wire and the base connector develop some fine corrosion build up. It may be hard to see yet that wire is loose at the crimp. I've seen this more so in 80's - 90's AC equipped Chrysler Products where the loose connection would even spark/glow causing more heat than it was designed to withstand. Upon replacement of any/all electric switches or connections involved with our Ford Heat-AC Systems, we use dielectric grease during reassembly. Hope this helps.

#908 of 915 Ford Rear Wheel Drtive Drift on and off the throttle by gseterry Nov 10, 2009 (6:13 am)
I believe you may have worn/failed Rt Rear rear lower control arm bushings, or worse - broken Rt Rear control arm anchor brackets. This condition is allowing your rear end to WALK forward on the Rt side under load and back (off load) in the 2 steer directions. Your car in essence is steering itself with the rear wheels. Have all these bushings (RT & LT - if they are the culprit) replaced. If the brackets have failed or are broken, have them repaired but inspect the LT side too ......... Good Luck. Terry

#910 of 915 Infrequently by euphonium Nov 10, 2009 (3:42 pm)
the CEL goes off and on while at highway speeds. It is a '94 Town Car, 145000 miles and runs great otherwise. What could be causing this?
#911 of 915 California emission test by tcb74 Nov 15, 2009 (10:44 am)
My 1984 town car did not pass the California emission test. To high on nox only at the highest speed measured passed everything else. I replaced the tps sensor(was bad) and o2 sensor. Can the bad tps cause it to fail alone?. Replies to this message: nwraaa (Nov 27, 2009 4:24 pm)

Replying to: tcb74 (Nov 15, 2009 10:44 am) Many Ford cars with that engine did not pass emmision testing when they were brand new. I put so much money into the emmission controls on a Lincoln that I bought during that era that the car should have been making oxygen. After spending at least a grand on the car and it would not pass, I took it to the Department of Motor Vehicles to get a waiver. That is when they told me that they hated dealing with that engine. They could not even get their own cars to pass emission inspection. The TPS, more that likely had nothing to do with it not passing. Your inspector simply may not have had the RPMs at the right speed to make the car pass. To get this engine to pass the following items need to be right: Clean air filter, weight of oil, grade of gas (they like Exxon and BP Premium), clean calalytic converters, hot spark plug, right on the money timining, new oxygen sensors, new PCV, and a can of gas system cleaner. If you do all the work at one time, drive the the car around at highway speeds for a couple of days before you take it in for inspection.
