Hi

Low pressure service point is on reciever dryer behind r/h headlight. Takes 0.470 kg refrigerant (R134a). Remove headlight to gain access (3 screws). Sticker under headlight.

Serviced the wife's 07 Fusion on nightshift last night. Same problem as you. Manufactures are not filling systems to full capacity when new. Doesn't take much refrigerant loss to stop the system working.

Hope this helps

Top man 'muddler1958' Thanks found it... :P Who would think to take the headlamp out.... :lol:

I would normaly discharge the system vacuum it out and recharge it, but I heeded your advice put my rig on and and went for the top up... it only took 2.5 grames of gas and the compressor kicked in its running about 35 psi on the high side. and chilling at 6-8 deg at vent after 3 mins and staying there does that sound about right?...

anyway I'm a cool cat now. not a hot head. thanks for the help and tip...Cartman690... :rolleyes: ;) :blink:

Temp and pressure sounds right.

Should have recovered refrigerant and drawn a vacuum for 30 mins before filling with refrigerant again to make sure all moisture removed.

Will do as a temorary fix though.

Hi

Recover refrigerant through low pressure port. Evacuate through high and low pressure ports for minimum 30 mins. Recharge through high pressure port. All with engine and AC switched off.

If no refrigerant in system suggest evacuating for 60 mins, then recharge with half fill and run AC and check for leaks. If no leaks top up to recommened fill.

Hope this helps
