What year is your car?

What was it you baught to put into your A/C?

Auto or Manual Climate control?

Have you checked the fuses?


Lets just start there.










Most likely your out of refrigerent. Why you lost it all is yet another issue.

 

I have a 97 GLE.. i think what i bought was refrigerant thing u said... i don't know how to check the fuses... i think my dad did.. but he was too busy... it's an automatic ... with the temp on the digital thing.. tellin' me the temp...

THanx...

what if i lost it all?

 

Do you hear any noises? Turn the car on, open the hood and when your in front of the car facing the engine bay, listen particularly on the passenger side. Let us know.

 

Uh oh.. i don't hear any sound from the passenger side...

 

That's good. That means its probably not the compressor (which can be and expensive fix).
1) You might have a blown fuse. An inexpensive thing to do yourself, but if you really don't want to, just take it to a local shop. Probably $20 max.
or
2) You probably just need some more "freon" or R-134. Take it to a local shop that does A/C systems (Yellowpages) and have them evacuate the system and recharge it. Shop around, its about $70 to $100 here in NC. They will also check for fuses if you want to do both ($5 for mine).

PHEW!!! YES... i will go to local shop to find out what's wrong.. yes!! thought not havin' a sound was bad.. phew

 

While we're on the subject, I also have a problem with my A/C. I feel that on highway speeds, when I rev the car to 4800+rpms, in that range, my a/c seems to turn weaken, then actually turn off, as if it needed to be recharged or cooled or something.

If I leave the A/C on around town, it's ice cold. But on the highway, esp. w/ spirited driving, the air actually gets quite warmish and humid. Does anyone recongnize these symptoms and know a solution?

 

i read somewhere the ac shuts down after a certain rpm or mph, can't remember. this was to protect the compressor, i may be wrong.

 

Hey Ferguson.. what size rims/tires are those on ur max?!?

 

17x7.5, tires are 235/45/17.

anyway, does anyone think they could help me out? I tried searching but couldn't find a specific answer.

 

I remember I read about the same thing also.

 

My AC works at high speeds so it shouldn't shut down.
Thanks,
Paul

 

If you floor it your AC will shut off. This is in order to give back lost HP from the blowers.

 

are you certain about this? I remember I've floored it many times in my auto, and the a/c air remained cold.

 

Yes, at WOT, the A/C compressor momentarily shuts off. Momentary shut off of the compressor will not affect the 'cool' level of your A/C because the compressor will come on shortly after. You can't stay at WOT for very long.
