So here is the scenario. I'm in Arizona and it's currently getting up to about 106 degrees. My wife's vehicle is a 2005 Mazda 6. When we pull up to a red light or if were stuck in traffic her A/C stays damn cold. However in my 06 F150, it will be damn cold while driving the truck because the air is forcing through the front (I'm assuming this is what cools it down more) but if I come to a red light or stuck in traffic and barely moving the A/C starts to warm up. Would Efans help keep my A/C Cold while stopped? Should I take the truck to the dealer and complain? Is this common?

 

Take it to the dealer and complain. Some of the trucks were low on R134 from the factory. Others have had the usual blend door, blower etc. problems that any truck/car may get.

My A/C works fine stuck in bumper to bumper traffic at 110 degrees.
I couldn't use the truck if the A/C wasn't good. And there are so many of these trucks here in the High Desert that if one in ten had an A/C problem the lines at the A/C shops would be two miles long. They are not.

Like chris said. There is no difference when using e-fans. I now no longer have a working A/C, that'll be fun. Just bring it in, much better than those cans and even not under warranty it shouldnt go over 75 to have a working A/C (59.99 for the check, 26.99 per lb is the going rate here). Even Jiffy lube can help with the A/C. 04's take just over 2lbs but they will reuse whatever freon they recover from your truck. 05-06's take slightly less.

 

Sorry, I forgot to mention that it sounds like your thermal fan clutch may be defective. The dealer can check that and fix it.

The clutch behind the fan is designed to engage the fan when it is hot, thus pulling lots of air through the radiators.
It slips when not needed, to save gas.
It slips when you are on the highway, again because a fan is not needed there.

Sitting at a light, engine hot, air hot, it should engage the fan and pull lots of air. I suspect it is 'clutching' or freewheeling the fan when it should be biting.

OK I will give the dealer a call and schedule a appointment, thanks for all the help.

 

This might finally be the explanation that would describe my A/C problems. On hot days when I’m stopped or in bumper to bumper traffic, my A/C occasionally makes a louder than normal “click” (clutch engaging/disengaging?,) the brake pedal depresses a little more and hot air starts to come out.

It’s been to the dealer twice and both times they can’t find anything wrong. The problem persists, though.

Chris, your theory might be part, or all, of my problem. Another suggestion a few folks have given me is that I might have a grounding problem.

Ugh…it’s hard to track down a gremlin.

 

I have the same problem.. However i installed E-fans on my truck, so now the dealer wont touch the A/C as the stock fan/shroud is no longer there.

I have a pretty good feeling that the R-134a is just undercharged. MY AC has always sucked since i bought it.

Does anyone know how i can get this fixed?

 

Take it to any auto repair place that does A/C. That is most of them in the country.
Catch it on sale, usually about 29.99-39.99 for service, plus any R134 you need.
Or buy a manifold gauge set, about 50 bucks most tool places.
Or find a friend with a set.
Or just take a chance and buy a seven buck rechange setup and toss some in. This would be my last choice.
