Hi There,

My 2001 trooper (4jx1) seems to not blow cold air when driving through freeways/highways where I need to maintain at least 1800 rpm for a minimum of 5 minutes. The rest of the trip will be very warm unless I drive under 1500 rpm. Seems like the compressor is cutting off immediately. This does not happen when driving through stop and go city thoroughfares.

I am from the Philippines so ambient temps would be at a 30-32C range.

I am not sure if my mechanic remove the engine thermostat as the highest warmed up temperature I've seen is 62C when before I see the number in the 80s (using a scanguage that's consistently connected). Is this a factor? If not, what needs to be done to solve the issue?

Thanks in advance! This forum has helped me in so many ways already. Smile

Thanks! I will have it recharged.

On the topic of thermostat, would there be any effect on other things (aside from not being fuel efficient) if the engine remains that cold?

Truly appreciate your responses, Eithan. I haven't found time to visit an a/c shop but when I do get to, I will update the thread.

Freon is now at optimum level. The a/c tech said it was a tad bit under filled. Same problem. Sad
