Heating AC and Engine Cooling

You have an exhaust leak and most likely the ventilation system is operating on fresh air mode and exhaust is being drawn in. BE WARNED exhaust is carbon monoxide and is a poisonous gas, get it checked and repaired

The computer. Controls the ground signal going to ur relay u should have no ground on the relay till computer sends the sivnal cheak that if u already did fuses .and relay the ground should. Be a green wire if u don't get ground install an independant fan setup its a setup that turns ur fans automaticallly.I forgot what its called that will kept u in junkin the car

Under the hood on the passengers side located in the a/c evaporator housing next to the blower motor and held in place by two screws...............

I have a 97 mercury sable, basically the same car. I found my low side connector on the firewall passenger side at the top. there is a high side connector sticking straight up next to the radiator refill, it is directly back from this. The problem I have is the recharge kit connectors do not fit. I am looking into it further and will post if I come up with anything, but the guys at the local auto parts store confirmed I had the right valve, but can't connect the recharge hose. Hope this helps.

On the top of the drier at the passenger side firewall Wrong the pressure switch is on the ac line under te air cleaner assl. There OS no drier on the fire wall it is before the switch .

I wish i had the answer my car is doing the same. Hope engine is not blown..

Power train or ECM? Most have been behind the passenger side kick board between door and firewall. you may have to remove cover beloe glove box first.

BAD RELAY answer bad switch bad relay and most likely, bad clutch

It sounds like either a loose ground or power supply, start by checking the connections at the blower motor............

I had the same problem with my 90 buick century, Replacing the temperature sensor did the trick, it is located above and behind the water pump.

The directions should be in a haynes manual you can buy at any auto parts store, i work at advance auto i know we carry them as well as autozone, i have a 99 grand prix and it blows cold only on one side so i am looking at the same thing, good luck

In the fuse box within the engine compartment it's the 10amp fuse nearest the front left of the car.

Your belt is worn loose or both. Check it and adjust or replace as necessary.

i dont know of any engines that started with AD

however

type 3

AN 1974 1800cc - 8.6:1 compression AT 1974 1800cc - European only, dual carb.

problem with you coolant level your engine isn't being cooled properly>>> ive had my engine over heat twice in the last week first one blown head gasket this one i don't know...

There must be a gas leak. Contact your gas supplier IMMEDIATELY, if the smell is in a house. If it is in a car, have your mechanic check for a leak.

I'd be suspicious of the thermostat.

I don't believe there is a fan relay in a Pac. The fan is controlled by an electronic circuit inside the air box, right behind the glove box. If your fan is stuck on "High" like mine was a few months ago its an easy fix and costs about $100 for the part from the dealership (the dealer was the cheapest). All you have to do to access it is empty out your glove box, bring it forward past the stops by pressing the sides in, and you will see an electrical connector right behind it held in by 2 10mil screws.

Most of the time it's behind the heater core you'll need to remove the dash in most cases to get to it best advice is if your going to do it your self get a Manual.

Could be a bad temperature sensor
Usually located at the rear of the radiator about 1/3 down from the top

Hi

The water pump (Just like a heart)pushes the water/antifreeze through the engine block, and through the radiator where the fins in the radiator absorb some of the heat, and the air passing through the radiator cools the fluid down to be pumped back into the engine block, keeping the engine cool enough to drive.

B.H.

Yes, the windshield defroster will turn the A/C compressor on.

Obviously you will have to replace the headgasket. Depending on the engine type and configuration, it may be a major process. Once the head has been removed you should take it to a machine shop to have it "planed", meaning that if the head gasket blew the head is probably warped and you have to do something to make it flat again. It can be out just a couple thousandths of an inch, something that you couldn't even detect, and that would be enough to cause the head gasket to leak. If you don't have experience with this, take it to a reputable mechanic.

If your talking about your blower motor for your cabin air system, they are usually located on the passenger side near the bottom of dash up towards the front.
