No Heat In The 87 Town Car

Hi Bill -

I have one more question - I have a 1987 Lincoln Town Car and my uncle and dad decided to change my heater core because it started leaking. Now I don't have heat anymore.

Thanx,

Bret

Hi Bret -

Sorry to hear that you have lost your heat after the heater core replacement. Some of those heater core repair jobs can be frustrating. I will assume that you had OK heater operation prior to the core change and will base my answer on that assumption.

It is unlikely but not impossible that another component has failed during the heater core change. The Temperature Control Sensor could have locked up in the full cool position and is causing the air to bypass the heater core but in my opinion this would be possible but not very likely. The engine thermostat could have stuck in the open position and is now causing the engine coolant to be overcooled. This has happened before. If the no heat problem was in fact caused during the Heater core replacement, then the fault lies with one of two things. The core itself is wrong/faulty or an error in re- assembly occurred. If a "used" core was installed it may be plugged. Vacuum lines may be re-installed incorrectly under the dash or the coolant level is low or air locked.

If what you are describing is only a loss of blower "fan" in the HEAT position and you have blower fan in the other control lever positions, this is usually caused by a failed Cold Engine Lockout sensor that is located in one of the heater hoses under the hood.

Their is no mechanic in the world that has not needed to occasionally "backtrack" or "double check" his work on a job to correct an error that occurred during his repair. I hope that the above suggestions help you and should you need any further help, repair parts or manuals please do not hesitate to contact us at any time.

Sincerely,

Bill

1987 Town Car Cutting Off While Running

Hi, Bill -

I have a 1987 Lincoln Town Car I have changed the water pump, starter, fuel pump, fuel filter, and the battery. I can drive it only for 30 minutes, and it will cut off on me but when I first got last year it never did. I really need your professional help because I do not want to sell it.

Hi Bret -

This is not an uncommon problem for us, but of course it is quite troublesome when it occurs to you on the road. Not knowing all of the details in your case though I can offer the following based on our experiences at Lincoln Land.

The sudden shut off of the engine is usually caused by a failed electronic ignition component at or inside the distributor. The electronic ignition that was used on your era of Lincoln is an excellent design but age and use causes these components to eventually break down.

George Miller here at Lincoln Land has also offered that he had a similar problem with his that proved to be caused by the ignition switch itself.

Another possibility to consider is a sudden and intermittent fuel delivery loss that is caused by a failing fuel pump, or its electrical circuit.

In any case and in the interest of time and frustration, the system has a problem that needs to be diagnosed properly by a competent experienced technician at a local "automotive tune up shop" so that only the faulty part is replaced. I hope that the above helps you on the path to a speedy repair.

Sincerely,

Bill

1969 Mark III Questions

Bill -

My Mark III will not change from defrost, to heat, to dash vents, and I cannot turn heat off. Also noticed the rear vents will not operate. Can you give me some direction and what parts I should check for proper operation, and do you have these parts? Do you have a repair manual for my car? I would love to visit sometime!

Thanks,

Marv

Hi Marv -

Very nice car and welcome to the Lincoln Land blog. We certainly would be pleased if you could visit our showroom and warehouse in Clearwater. You would be able to meet us and to see some very nice Lincolns and FORD literature that we have for sale and on display for fellow Lincoln lovers.

The description of your a/c problem sounds 99% like a classic loss of vacuum to the Climate Control and the Flo Thru rear vent systems. Loss of vacuum will cause the system to drive and default to full defrost and max. heat with the fan at high speed. The rear vent will also become inoperative at the same time. The Shop Manual set is very explicit on these complicated systems and is an absolute must in order to quickly diagnose the vacuum and electric features of all 1969 FoMoCo vehicles. If you wish, we can arrange to have a set sent to your address. I hope that the above helps and if you need any further advice or any parts to correct your problem please do not hesitate to contact us at any time.

Sincerely,

Bill
