Question about 1995 Pontiac Grand Am

1 Answer

Accidently unhooked a pressurized line when changing heater core. I believe it is an ac line however my 134a level is reading full. There are 2 lines next to each other. I unhooked the smaller of the two lines. Can someone please tell me what I unhooked, and what I need to do after I hook the line back up.

Normally when you unhook an ac line you purge the system and recharge it. You probably unhooked the high side line from the compresser is my guess. If your system is full (ie you have a gauge pack), and the temp is correct at the outlets in the car, then I suppose you could run it. However, I do not see how your system could be charged since you unhooked the hose...If your temps are not cold in the car, a shop or a lot of oil change places will recharge it, or you can buy the 12 oz cans at the parts house. Hope this helps you, Rick

Ford focus se how to repair


invest in a can with a gague of 134A at auto zone it will have the filler hose on it. Attach it to your low pressure side line .it will only fit on the low pressure side. (if you cant find low pressure line on car google (where is low pressure line for AC Ford focus) check your gauge if low on R134A add some from can .If all is ok check ac fuse. if nothing works after makeing sure system is full of 134A check if your compressor is working. usually it just needs to be recharged.

Engines can rock on the motor mounts. You probably have a vacuum line that is pinched, cracked, broken,kinked, or unhooked. check the engine compartment lines first. If you have thin plastic vacuum lines, they can kink more easily than rubber lines. If you have been working under the dash (replacing a radio, etc) check your work area in case you have a broken fitting on a vacuum housing or an unhooked line.

No heat, changed the thermostat, no luck


If the thermostat is ok and you've got a full coolant level, next try touching the water lines going through the firewall to the heater core. Both lines should be hot to the touch. If only 1 is hot, you have a blockage in the system. If both lines are hot then you may need to replace your heater core. Also have a pressure test done on your cooling system before you go spend a lot of money because you may have a problem there which would prevent enough pressure from building up to push the hot coolant through to your heater core.

1995 pontiac grand am: AC


You take your car to the nearest licensed automotive A/C shop and have them evacuate the system and recharge.

I'm saying this because once you have opened the system, you have let moisture into it. Even a small amount of moisture will damage your A/C system, and needs to be removed. Also, they will know just how much refrigerant to put into the system once it is moisture free.

Follow these steps:

Check coolant level, then start engine until it is warm and the thermostat opens. You will tell when it does when the needle on your temp gauge goes cold when it reaches around 180-200* and then goes back up. Now turn on your heater full blast and go to the engine compartment. You will see a heater valve located on the passenger side, next to the washer reservoir. It is a black thing with 4 heater hoses connected to it. Feel the hoses. When everything is working correctly it should be like this:

Hose going to waterpump will be hot
Hose going to (I think the thermostat housing) will be hot
2 Hoses going to heater core (mounted behind firewall) will be hot

1. If only 1 heater core hose is hot, heater core is clogged--
UNCLOG: remove 2 hoses going to heater core when engine is cool, hook water hose end to one of the sides and flush out gunk from heater core. Reconnect hose and you should be good.

2. If neither hose core hose is hot, heater control valve is bad or vacuum is bad--
Test Vacuum: remove vacuum line from heater control valve, you should feel the vacuum **** on it when pressed to your cheek and the heater control valve actuator should move when you unhook the vacuum line. If you have a good vacuum, it's probable the valve available at autozone part # 5941 for around $21.

To get heat while you wait to replace part, unhook silver arm on heater control valve that is hooked to the plunger. This will give you heat all of the time, but it is controlled by the bottom hot/cold switch on your heater control unit so you won't get hot in the cab. It will just circulate heat through the core.

Air conditioner not cooling


Is 1 of the 2 AC (under the hood) lines cold? if so you may have a blend door problem, that door is in the dash air duct distribution system, it mixes are between the hot heater core and the cold AC evaporater core to give the set or desired air outlet temp, When you turn the defrost on does it blow hot/cold as the lever is moved back and forth? The compressor turning off and on is normal cycling of the system, when it reaches a preset pressure in the low side line, a pressure switch will open and compressor will "cycle off" when the press starts to rise to a preset limit the compressor will "cycle on" and so on. I assume you have an electric bled door, older cars and trucks use a cable operated mechanical door.
