Year: 2004
Make: Ford
Model: Explorer
Engine Size: 4.0
Refrigerant Type: 134
Ambient Temp: 85F
Pressure Low: 18-50
Pressure High: 125-150
Country of Origin: United States

Over past few months the car has developed poor cooling. Compressor runs for 20 seconds or so, then the low side hits 20psi and the compressor cuts out, the pressure climbs, then 15 seconds or so later the cycle repeats. I went over the engine compartment with a black light, but don't see any signs of dye. Are there any common "weak points" on Explorers that I can focus on? Also, how hard is it to get where I can see the evaporator core with the black light?

Common leaks are the corners of the condensor and the compressor front seal.
