SOURCE: AIR CONDITIONING: COMPRESSOR STOPS WORKING
a switch is triggering your ac module to stop the compressor. it could be coming from your high pressure switch or your low pressure switch. you could have a clogged system or a low on gas system. i could only diagnosed it more if you can provide me with pressure readings of the high and the low side of the system while running on idling.
you can observe when the light will flash. is it while driving?, on high speed/..or low speed?..or even just on idling.?
i hope i was able to answer your inquiries
let me know if you have any more question..
pls rate me...
tnx..

yes there is a relay under the hood, usually located in the power distribution box and if that doesnt fix it, try checking the low pressure switch, located on the accumulator or the low pressure line. You can check this by unplugging the two wire pigtail and completing the circut with a paperclip

first the a/c issue is probably due to low charge. Need to recharge, if you still had R12 in there you need to have it updated to R134A or find someone who has R12 which is tough.
Starting issues are tough to explain without more info but if you mean your starter doesnt turn the motor I would suggest a new battery as you probably have a weak one or it has a bad cell. If your starter turns but it wont start could be the OVP relay, the cold start vale or any number of ignition parts from the coil to the plugs.

The refrigeration system in all vehicles should be repaired by a certified HVAC technician or equilavent. Dealing with R134A the refrigerant used in your vehicle is dangerous. The electrical checks to determine the repair are difficult and depending on what the problem is are costly and may involve removing the refrigerant with special machinery
to replace a sensor or major item in the system.
Lastly in most states its illegal to purchase refrigerants and /or render repairs on a/c systems without the proper certifications.
In your case it appears that the blend doors or blower motors are not working because you stated in your write up that compressor is on and refrigerant is a-ok.
Have a technician check this out. May have to remove dash board to do testing. This is money well spent.

You could have the beginnings if a malfunctioning Blower Motor which is located under your passenger side footwell. Have it tested first to determine if it will run continuously. if it does than check the A/C relay next.
?€¢
MAF: A Mass Air Flow (MAF) sensor output that causes the PCM to sense a lower than normal air flow will cause a lean condition.
?€¢
Air Induction System: Air leaks into the induction system which bypass the MAF sensor will cause a lean condition. Check for disconnected or damaged vacuum hoses, incorrectly installed or faulty crankcase ventilation valve, or for vacuum leaks at the throttle body, EGR valve, and intake manifold mounting surfaces.
?€¢
Fuel Pressure: Perform a fuel system pressure test. A faulty fuel pump, plugged filter, or faulty fuel system pressure regulator will contribute to a lean condition.
?€¢
Injector(s): Perform injector coil/balance test to locate faulty injector(s) contributing to a lean or flooding condition. In addition to the above test, check the condition of the injector O rings.
?€¢
EGR: Check for leaking valve, adapter, or feed pipes which will contribute to a lean condition or excessive EGR flow.
Reviewing the Fail Records vehicle mileage since the diagnostic test last failed may help determine how often the condition that caused the DTC to be set occurs. This may assist in diagnosing the condition.
