A/C problem when driving on the highway
Hello,
My A/C doesn't work fine when I drive on the highway, sometime the A/C pump jump off, sometime it just not cool enough, what do you think??
1. my car works on 220 temp on the highway. (too hot???)
2. I added 2 more fans working together with the stock one.
3. I don't have air dam.
4. The A/C pump is not new but work fine in downtown.
Thanks
Joe

Get an air dam.
A quick guess: The freon is low. So when you get the engine running a faster rpm(down the highway) the low pressure switch kicks in and out.
