Hello;
You probably have a leak and are oout of refrigerant. The R134 needs to be installed back in. You will need to vacuum down the system and check it for leaks. Repair as necessary. Hope this helps;

Knocking noise from motor when you turn a/c on it goes away Also car is over heating what could it be


check the ac compressor mounting bolts for tight the reasoning is that when the ac is off ,the drive belt is relatively loose as the pulley is just an idler but when you engage the ac clutch the belt tightens to drive the compressor and holds the compressor tight against the engine
over heating can be fro head gasket/cracked head---compression test
partially or blocked radiator--replace
low coolant level--check at radiator cap and fill
bad radiator cap--replace
thermostat fault-- check or replace
air lock in coolant system--- bleed air oit
transmission oil overheating putting too much heat in the radiator from the oil cooler (auto trans.)
failed cat converter blocking exhaust--replace
timing --check adjustment

Check that the heater is turning off as the hot air will over come the cool air. Check that the clutch on the a/c pulley is still engaging as it the unit was over filled or has a leak from a badly fitted pipe the high low switch will not allow the compressor to work.. If the work was done professionally check that the correct gas was used and seek warranty for the problem.

Engage ac or defrost or vent I get a pitch squeal and nothing works.Compressor?


Yes, except for the vent setting. AC or defrost will engage the compressor, but vent should be just outside air.

I ust had the water pump replaced. Now my ac has gone out. I know nothing about cars but I do know that I hear a strange noise and the front part of the ac unit was turning and now it's not. It seems...


It is unlikely that the replacement of the water pump and AC failing are related, however ensure that the V belt is correctly positioned and under tension. The AC pulley should be spinning continuously by the V belt. The AC compressor is engaged by an electrically operated clutch within/behind the pulley wheel. If the pulley wheel is not spinning but the belt is sliding over it then you have a seized AC compressor and this will most probably need replacing. If the wheel is spinning but the AC compressor is not working (no cooling) then it is the clutch that is not engaging. This could be due to a worn clutch, failed clutch actuator, broken electrical connection, failed relay, broken fuse a failed interior thermostat (the car thinks that the 'set' temperature has been reached and so switches the AC off). To check, put the AC on the lowest setting and test the voltage at the AC compressor connection. If voltage is being supplied it is likely to be a failed AC clutch. There are lots of AC clutch repair videos on youtube and these should be a great help.

The engine of my bmw 5 series 2003 model is vibrating whenever i on the air condition, what is the cause and the A/c will cool at-times and not cool at-times but suddenly it stops cooling yesterday,


ask a local mechanic with a proper AC regas machine as i think you may have too much gas in the system ,it will need emptying and regassing to the correct weight of gas

AC blowinghot air


Locate wires coming from compressor clutch and trace to nearest plug that you can unplug. Turn on A/C to max cooling. If clutch not engaged (center of compressor drive pulley not spinning with pulley), unplug compressor clutch wires and use multimeter to check voltage going to compressor clutch. If voltage is around 12 volts or more, then clutch should be engaged when plugged in. Plug clutch wires back in (with motor still running and ac set to max). If clutch still not engaged, then clutch definitely bad because 12V signal should engage it.

My 2002 Expedition air conditioner will sometimes blow hot air and others cold air


I would check the following possibilities:
1. Is compressor clutch working? - You need to do this when the ac is blowing hot air only - locate compressor drive pulley on engine - rubber belt wraps around it. Start engine and set to max ac. When the ac is blowing hot air, look at the center of the compressor drive pulley using a good flash light - watch it for a while, it should be spinning with the pulley - this means the compressor is engaged. If not, the compressor is not engaged. If your ac is blowing hot air, then the compressor should be engaged and running (trying to cool). If it is not engaged, then your compressor clutch is probably going out. Could be low voltage to clutch, but more likely the clutch is worn out and only working some of the time. Note: if working normally, the compressor clutch will engage and disengage in cycles- but the air should always be cold. If clutch is bad, compressor would need to be replaced (sold as one unit). This is tricky to diagnose and could take some time - you need to do it when ac is blowing hot air but set to max cooling.

2. Low on refrigerant or refrigerant has moisture in it? If your ac blows cold initially after being off for a while, then heats up, and continues to regularly cycle back and forth between hot and cool air, then the system may be low on refrigerant or the refrigerant may have moisture in it that is freezing and restricting refrigerant flow. An a/c shop can check refrigerant level and even replace refrigerant if moisture is suspected.

Could be other issues, but I would start with these.

Good luck

2002 eclipse heater blows cool air


Check your antifreeze level and if low then add antifreeze until the radiator is full and the overflow tank is up to the correct level. that should solve your problem. If it isn't that, chances are your thermostat could be stuck open which isn't allowing the coolant to warm up properly.

Good Luck

Heat not working or diles


You most likely have an air pocket in the cooling system. The heater core on these vans is much higher than the engine and they can be tough to get all the air out of them.

Make sure the coolant in the radiator is full when engine is cold- also fill the overflow bottle to the top. Chock the rear wheels. Jack up the front of the van as far as you can and support with jack stands. Run the engine until it's warm and then hold the RPMS at 2000 for about 5 minutes while checking for heat inside the cabin. You may hear some funny noises like something is trying to come through the firewall forcefully! That's the air pocket moving... you might not hear this also. Once you have good heat inside, let the engine idle- if the air coming form the vents cools off after a couple minutes, the air is still there- keep doing this until the air is hot coming from the vents at idle for more than a couple minutes. Once you have good heat, turn the engine off and let the engine cool completely- at least a couple hours... you will most likely see the level in the overflow drop dramatically. Lower vehicle and make sure overflow is at COLD FULL mark.

Newer Altimas also had a similar situation in which heat would go away at idle- usually not a problem with an air pocket, but Nissan has a bulletin out on putting the correct concentration of coolant/water in the system- these cars are very sensitive to changes in coolant mixture concentration.
