I have a 2006 mitsubishi lancer. The a/c works intermittently. Works the least the hotter the day gets. The presures are 25 low side & 145 high side @ idle. What are the proper pressures ? I beleive this systems runs @ lower pressures than the older cars. The high pressure switch works & cycles the cooling fans. the compressor sometime cycles and not @ others. Does anyone know of any usual suspects??

You can't guess with this vehicle take it to Auto-Zone they will check the code for free and get back to me. Good Luck

SOURCE: air conditioning compressor will not kick in,

If it is above 100PSI, you are over charged. Any thing under, should be normal to low. You probably need to get it checked by a professional to make sure it has the correct charge, and the compressor is getting power when the switch is turned on.

I had the same problem in my Saab. Replace the column with the buttons and you should be good to go. Check with eBay and local junk yards for the part.
