The anser is yes. The refrigerant is in the A/C system which is independant from the heating system.

My 2008 dodge ram temp gauge goes from normal to high ,check gauge lite comes on in a few minutes temp gauge goes back to normal but heater will only blow cold air I,ll shut heater off wait a few minutes...

Souds like it's way low on coolant. The heater will blow cold air when the cooling system is so low that there is no water (coolant) running through the heater core. Then the thermostat opens, it trys to be normal but the system is low so it gets too hot in just a few minutes. If its that low, there must be a leak somwhere.

My heater in my 2007 sonota stop putting out heat what could be the cause of that

most likely you are just running low on coolant/antifreeze . if it is low the coolant cant reach the radiators wich are used to deliver the heat.

Runs hot and hearter not blowing hot air

a heater uses the temperature of the cars water, running threw a heat exchanger if the heater core has failed water will not circulate threw the engine properly this will and can cause over heating as well as nothing blowing from the heater. good luck.heater cores are generally inexpensive parts to replace.

last thing you can check if heater core is ok. is the thermostat.

Heater not heating on 2002 suburban fan blows just does not heat up any ideas culd it be a relay switch

No, Relays control the fan running. But you said it is running. Low coolant level, clogged heater core or sticking temperature door could be the problem. Is the engine running at normal temp? Open thermostat could cause low temperature.

Ac unit only works sometimes in 98 accord

Check the amount of refrigerant in the system. If thats ok, you might have a bad pressure switch. If the system is full. Find the low and high pressure switch. Run the ac with just the high press swith unplugged. see if the problem occurs. Do the same for the low side. More than likely if your system is full on refirgerant, and trust me I would check that first. Could save you alot of time. Then it could be a pressure swith, and a simple test like that can tell you. But in order for that to wirk you maust have the ac system fully charged. NOT OVER FILLED WITH SOME ADVANCE AUTO PARTS ****. Go to a tech and have them do this correctly.

2001 Chrysler Voyager - A/C won't engage

This definately sounds like the clutch cycling switch or the low pressure switch is bad. You just simply evacuate the system, screw off the old and screw on the new and then evacuate and recharge the system. This should get you fixed. You might also want to check and make sure that you have enough refirgerant in the system. If there is not enough then this switch will not allow power to flow to the clutch to prevent any damage to the compressor from there not being enough oil in the system.

Engine hot ... heater cold ?

Check the coolant level, it could be as easy a fix as adding coolant because it's low. Low level causes engine to overheat, and low level won't circulate to heater core, so no heat situation even though engine is running hot. Let me know if this fixes it, if not I'll help .
