1977 Continental with multiple issues....

Hello Bill,

I have a 1977 Lincoln Continental Town Coupe. It has a couple of issues, some I have addressed, some successful and other not so. Installed new, not refurbished carburetor, new master cylinder, battery and A/C compressor and have the A/C system converted to the new R-12 coolant. My lingering issues are brake light came on on the dash, break pedal seems to be not as positive as before, car still does not start as it should by setting the choke as instructed in owners manual. I have to pump and pump the gas to get it to start. A/C still does not blow cold; I have a shutter when I apply power to the car. I checked the drive shaft and the two piece drive shift universal joints seem loose is the fix, to just change all four joints? Another question is do I have to take the steering wheel off to get to the light bulbs behind the gauges behind the dashboard?

Thanks,

Ted

Hi Ted -

Those 77's are real nice running cars and when all of those problems that you are describing are eliminated from your car yours will be too. The brake light warning light remaining on is USUALLY one of the following. 1) Improper bleeding of the hydraulic brake lines, or failure to bleed at all after repair. 2) Loss of hydraulic pressure in the front or rear lines. 3) Internal failure inside the brake master cylinder. We have never needed to remove the steering wheel to change any bulbs behind the dash although some bulb changes may be difficult.

Your other problems can only be diagnosed with more information from you or actually seeing and hearing the component operate. For instance, for your Air Conditioning problem the R12 refrigerant that you mention IS in fact the original refrigerant. There are several substitutes being used by AC shops and I do not know what was installed in your system or the condition of the other components in your AC system. These AC systems are diagnosed with the use of AC gauges hooked up to the high side and low side lines and the pressures are checked and evaluated along with the outlet temperature at the vents inside the car. The problem could be a control problem or an actual refrigeration problem. Any one or more of a dozen or so faulty conditions are possible here that can cause poor AC performance. Your other symptoms also require knowledgeable on scene diagnosis by competent technicians. If we can receive detailed information from you regarding these problems, we may be able to assist you further.

Sincerely,

Bill
