Question about 2001 Lincoln LS

1 Answer

2005 LS Jag engine - air conditioning works on long trips sometimes, then all of a sudden we get no cold air and the air flow reduces to about nothing. I stop the car (gas station for 5 minutes) and go again - most of the time everythings runs ok for another 1 hour. Whats wrong? I do hear a small whining noise, but the blower motor seems to be working on high w/o much air back into the car.

    I have a 2000 Lincoln LS V8. I had it in storage for two years, recently took it out to drive it some. It missed quite a bit at first, but after running a couple of tanks of gas and injector cleaner through it, that has mostly resolved. The problem I have now is that the air conditioning works real well for about 5 miles then quits. Not only does it quit blowing cold air, but very hot air comes out of the vents. If I stop it for just a few minutes it will work fine again for a few miles, then the hot air again. I had the "freon" charge checked, no problem, it's not low. The local mechanic has no idea what's going on. Anyone have any ideas short of taking it to the dealer which I fear is going to be very expensive.

Sounds like your evaporator is freezing up.There are several things that could cause this like low freon charge,restricted orifice tube,ambient air temp sensor,evaporator discharge air temp sensor,AC pressure transducer sensor.
You might want to get someone experienced on that vehicle to take a look at it.

2003 jag s wont start, hit in rear panel, no rear damage, nersha switch to trip was re-set.Door, lights work- windows d/n roll up/down-cannot shift out of automatic.Steering wheel,ignition key turns


Hello Margaret,

From what I gather, at a certain g-force deceleration (collision) this switch (the inertia safety switch) is tripped shutting off the fuel pump.
I have also read that even when the inertia switch is tripped in a accident, the fuel pump sometimes will still function normally.

If your vehicle s a North American model the first place to start is a code scanner to see if any fault codes have been logged.

'Regular' OBDII scanners will only capture engine and transmission codes, all other advanced systems like ABS, air bags, body modules, etc will require a more significant software/scanner. Right now the autoenginuity scanner is currently the most affordable and effective scanner for the jags standard and enhanced codes.

If your inertia switch has been re-set I have read in some blogs that disconnecting the battery will sometimes clear up unusual conditions.

Whre's the location of Mass Airflow Sensor in a 2005 Lincoln LS, V8?


Located in the air intake tube drivers side of vehicle. In Line with air filter housing top. Most of the time mass air flow sensors get debris inside them from an unsecured air filter housing. Sometimes they are tough to clamp housing back correctly

My 2005 Malibou Maxx ls loses power without warning. Sometimes it happens when it is cold but yesterday I had been drivving for over 1/2 hour before it suddenly stopped. It doesn't happen every time I go...


can be a sign the cam or crank sensor is on its way out, can also be a dirty MAF sensor. cam sensor will make the engine run ruff, MAF will make engine ruff and not idle properly, Crank sensor if it fails it shuts engine down as it dont know were the engine is at on its cycle. air filter changed or replaced damage air filter will coat the maf with muck and it will need cleaning off the sensor, easy to do with MAF cleaner. sensors they can fail when they to hot for them to run anymore or to cold. the resistance in the sensor goes up and down in different temperatures. some time when it goes completely out of range the engine light comes on, but a failing one that is still in range makes the engine run out of order.

05 Lincoln LS 3.0 V6. Outside air temp 32F. Idle decay when cold


This sounds like you have a pcv hose that has become an open vacuum leak. It is located under the upper intake, or given the year your air filter box may not be correctly sealed and possibly have a mass air flow sensor concern. Any Check engine light or codes to work with ? I f you have further questions just leave a comment on my page,

Can the mass air fow sensor cause hesitation when accelarating?


Yes it could be bad sometimes cleaning it works and sometimes it doesn't. You should wait for the light to come back on and get the code before you buy a MAF sensor as it is expensive. You need to replace your air filter because that is likely that the fibers came off of it. You need to use a high quality stock replacement air filter.

Lincoln lse 2005 ac blowing hot air on left side!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


If your LS is blowing hot air on one side of the dash and cold on the other the problem most likely is the Dual Coolant Control Valve. The DCCV is used to control cabin temperature. This valve is mounted down low on the passenger side of the radiator fan shroud, and has 3 coolant hoses connected to it. This valve if found to be faulty will need to be replaced to correct the condition.

My 2001 lincoin ls gauge goes up to the h and then come back down


you probably have air trapped in the system. Have dealer or radiator shop bleed system.

I assume your cooling fan is working.

what engine v6 or v8?

SECTION 303-03: Engine Cooling 2001 Lincoln LS Workshop Manual
DESCRIPTION AND OPERATION Engine Cooling The cooling system components include the:
  • block heater (optional)
  • cylinder head temperature sensor
  • fan blade, fan motor and fan shroud assembly
  • radiator
  • pressure relief cap
  • degas bottle
  • radiator draincock
  • water pump
  • oil cooler (optional)
  • water thermostat
The water thermostat:
  • controls the engine coolant temperature.
  • allows quicker engine warm-up.
The degas bottle:
  • provides a location for system fill.
  • contains coolant expansion and system pressurization.
  • provides air separation during operation.
  • replenishes the engine coolant to the system.
The fan blade draws air through the radiator to help cool the engine coolant.
The fan motor:
  • operates only when the engine is running.
  • will not operate when the engine is off.
The engine coolant flows:
  • from the lower radiator hose to the water pump.
  • from the water pump to the engine block and the cylinder heads.
A closed water thermostat returns the engine coolant to the water pump. An open water thermostat allows the engine coolant to flow to the radiator.
Unsatisfactory coolant materials:
  • Alcohol-type antifreeze does not provide adequate water pump lubrication.
    • has lower boiling point
    • reduced antifreeze protection
  • Alkaline brine solutions will cause serious engine cooling system damage.
The cylinder head temperature sensor provides a signal to the temperature gauge.
  • will invoke failsafe cooling.
The optional block heater:
  • electrical heating element is installed in the block cooling jacket.
    • uses a standard 110V (220V in Europe) electrical supply
  • keeps the engine coolant warm during cold weather.
The auxiliary water pump (3.9L only):
  • provides heater coolant flow boost.
  • has a secondary function of providing engine-off cooling.
