Best thing to do before doing anything else is check the outlet temperature at the vents. If mine is working fine I won't touch it. Today in 90+ degree temperatures with 90+ percent humidity, the AC in my Echo was cooling fine at max cold thermostat, recirculate and lowest fan speed. When moving down the road it cooled well enough to increase the temperature setting and still be comfortable.Thanks for the replies. I got an ac manifold and vacuum pump and hooked them up. Now, the compressor wont turn on at all.
Here's the full story. The ac was working fine but i decided to top off the freon with a quick fill. The gauge was apparently off and i overfilled it. The compressor would turn on for a few seconds and then turn off. After seeing the posts, i hooked up the manifold. The low side was at about 110psi and the high side at about 100. I vacuumed them both out for an hour or two and now, the compressor wont turn on at all, so i cant even fill it back up. Is there something i'm missing that needs to be done?
you're supposed to charge the system with the car running and the AC on. And are you using gauges or are you still trying to fill it with one of those quick-charge low side only kits??? 95psi sounds way too high for the low side.... Why did you fill it that high?I tried again and the compressor doesnt turn on. After vacuuming for 45 min, i connected the freon to the low side. It went to 95psi and i started the car with the ac on. After 15 min, the compressor still is off. Any ideas? Thanks
If you filled it with the car turned off then you didn't do it correctly. Also Idk what you mean by the can sent in 95psi worth of freon.I followed the video exactly. Vaccumed it and then connected the freon with the car off. Then, opened the low side on the manifold with the car off. The low side jumped to 95psi because thats what the can sent in. Then, i started the car and turned on the ac. But the compressor isnt turning on. It worked last week before i ovefilled it.
