Before you $pend big buck$, first check if the vents are blowing warm air with the AC off and the temp all the way cold. My 2009 fortwo was doing this and it ended up that the flapper valve that mixes the air was being held open by debris (leaves) a little ways on the heater side, so hot air was always getting through. Much easier to check this before going after more expensive repairs.
Anyway, to answer your question, the suction (low pressure) fitting is behind the front passenger side turn signal. Remove the grille and then the turn signal and you should be able to access it. If you have huge hands like me, it's a tight squeeze. I ended up attaching a flex hose to the fitting and moved it to a more accessible spot...
Hi, the reason for this is the location of the evaporator core, its on the passenger side, a low charge will cause the side nearest to core it to cool more. Your cycling of compressor concures with this scenario. Recharge system to specifications.
Freon is not full. If it goes back and fourth it is pumping then reaching a low pressure on the low side below 35 psi. Pressure while car is off should be pegged. Check at idle should be around 50 psi and 35 psi at 2000 rpms.
Good luck. If problem persists evac system replace dryer and recharge.
Hi, determine if your car uses R134 or R12 refrigerant. You will notice screw type connectors on the both the High Pressure Side and Low Pressure Side lines in models using R12 refrigerant. R134 compatible models have quick connect valves on both sides. Models made before 1995 may use the old R12 refrigerant. If this is the case, you must have your Chrysler's air conditioning system retrofitted to use R134 refrigerant. Mixing R12 and R134 refrigerants is dangerous and may cause damage to your vehicle.
Check your air conditioning system pressure using an automotive air conditioning pressure gauge. Keep in mind that in order to get an accurate reading, the air conditioner has be turned on the coldest setting with maximum blowing power.
Remove the Low Pressure Side port valve cap and set it aside. The location of the port varies, but it is usually in front of the engine block. Attach the refill hose to the port on the Low Pressure Side of the air conditioning system. The Low Pressure Side port is smaller the High Pressure Side port. Because the ports are different sizes, the refill kit hose should fit only on the Low Pressure Side port. Additionally, the High Pressure Side port will usually have a red cap or be marked with an H or the word High
Allow the air conditioner to **** the refrigerant out of the can by slowly turning the valve on the refill kit hose. Pay attention to the way you hold the can. Most kits will have you hold the can upright when you recharge the air conditioning system. It may take as long as 10 minutes to empty a single can.
Turn the valve to the off position and remove the refill hose from the port. Recap the port before closing the hood.
Let the air conditioner stay on for at least 30 minutes. This allows the refrigerant to move throughout the entire system.
Sounds like the A/C system just needs to be recharged. When was the last time you had this done? Just take it in to your mechanic and he can do it for you and if that's not it for some reason, then he will be able to find the problem but most likely you need more freon added.
The one closest to your AC compressor... i.e. the part that the belt spins around.. Is the low side.. Not to mention, air conditioning recharge hoses ONLY FIT on the low side.. Worst case scenario, try both.. the one that it clamps down on to is the low side..
