Have a 03 TB LT 3rd row and rear ac. 230k miles 4x4 runs like a top. The ac lines to the rear had a hole I replaced a section and am getting a low side of 49psi and 215psi on the high side wondered what the specs are on the pressures is the main reason for my post. The front blows cool but the rear isn't much cooler than the inside truck temp. I had the problem of crappy ac when stopped in 85-90 degree temps but I installed an additional fan on the condenser problem solved for 30$. I have fixed the rear stabilizer links after repairing the mounts,iridium plugs, replaced the spare tire lift, spliced and replaced a section of ac line, trans filter,front and rear diff oil, and a hub bearing. She's road worthy and seems to run great.
