SOURCE: coolant smell when defrost is engaged in hot setting

There is only one possible cause to this easily diagnosed symptom. Any mechanic will tell you: the heater core is leaking. This is why the steam is rising up to the windshield, and why you are smelling coolant. Your heater needs to be replaced. There is not quick fix, just replacement. Hope you can get this done soon. Heater cores are nice to have during winter weather. Steamy windows aren't easy to see through, and are hard to defrost! Thanks for the question. Good luck. TT

it is on the fender near the battery and is also referred to as the starter solenoid (if you follow the large wire from the positive terminal of the battery at the other end will be your relay/solenoid)
hope this helps!

front of engine down low on passenger side (access from under the car), there is no AC delete option so the compressor should be there and not bypassed, what is the question about the AC? it doesn't work?

you could have. Take a look and find out. If the lid/cover of the fusebox does not name the fuses and relay's check owners manual, find the fuse(s) and/or relay and check it out.

Relay can be tested in a few ways,

first, easiest way get a buddy to go in the vehicle and switch your AC on and off, find the relay and get in real close and listen and feel for the relay clicking as he turns it on and off, if the relay is clicking it is most likely working fine.

if you are unsure on relay working you can try this method: theres usually 2 switches one is normally closed one normally open. Using a multimeter and the electrical diagram that should be on the side of the relay itself you should be able to figure out which switch is normally open and which is normally closed. Look carefully sometimes the writing, labels and numbers are hard to see.


Another possible cause is that your temp sensor failed so the computer thinks its -40 degrees and therefor won't run the fan. check the temperature sensor wiring, and the sensor itself after you look at fuses and relay operation.

Hope this helps :)

you may need to top up the coolant,r112,r140or what ever the car is useing. if the car can'nt be topped up then you have a leak that needs to be fixed,usually the drier.

My 2001 mercury grand marquis with 89k, revs hi and low when the ac or the defrost is on, when they are off the car runs real smooth


This is normal. The PCM kicks up the RPM's when the A/c compressor is on. If the compressor is constantly on and off with the A/C on, check for low freon.

Im trying to replace an ac compressor cluth with a bypass but cant find anything that tells me how


The major autoparts stores sell a bracket which uses the same boltholes as the old A/C compressor. It has a free-wheeling pulley and should use the same belt.
There are a few potential problems, I see, which may be noticeable in engine idle speed. When A/C worked, or Defroster, the drag of the compressor running was to be offset by a bump in the RPM to offset drag. You will need to tidy up the loose hoses to keep them from dangling in the engine compartment.

Air conditioner compressor will not turn off.


The low pressure switch cuts power to the compressor if the pressure drops below 20psi such as when the system is low on freon.
If the compressor runs with the HVAC system in the off position, you would check for a stuck relay, or a short where the compressor clutch is getting power from another source.

A/C compressor not coming on 1996 Mercury Grand Marquis


The first thing to do is check the connector at the AC compressor to see if it has power whwen the system is turned on. Then check the pressure switch as well for power in and out.

Ac on 96 grand marquis continues to blow hot air with new compressor and freon?


The first question is do you know if the ac compressor is running ?
If one ac line is hot and the other is cold you may have a blend door problem under the dash.

Condensor on compressor wont engage,,,1996 mercury gran marquis


relay should be located under the hood next to the battery. There is a fuse panel with many different relays. Check in your manual under "roadside emergencies" and find the relay for the A/C compressor. very common problem.
