Question
QUESTION: Hi, I have a 2007 Dodge ram 1500. The a.c. randomly stops and starts when ever it wants, mainly it stops when i start it some times and will then just turn on while I'm driving. My 2001 Jeep Cherokee did the same thing but i traded it in and didn't worry about it. Please help.

ANSWER: Hello George
I need you to be more specific with the problem please.

To eliminate the basics, has it got gas, and if so does it have enough ?
When it is not working, does the interior fan stop as well
When you say it works when it wants, how do you know this. Is it because you can hear the a/c compressor cutting in or because it blows cold air randomly ?

I am sorry this probably does not appear very helpful, but it is not clear to me what exactly is starting and stopping

Please advise

Thank you
Paul

QUESTION: It has plenty of gas, the a.c. does not blow. When I'm driving I can feel the air passing trough the vents is cold. What I mean by works when it wants is that I will start my truck and the a.c. wont turn on , so i leave it on then randomly it will start blowing and some times it wont it will start working on the next time I start it(some times)

Answer
Hello George
On a climate control system this could be something like a temperature control sensor sending the wrong reading to the fan
On a simpler system this sounds like a feed issue of some description

Ask an auto electrician to take a look. We are uk based with no specialist knowledge of your vehicle

Expertise

Any question related to the function or malfunction of vehicle air conditioning excluding model specific problems with the heater controls. We are a UK based company and are unlikely to be familiar with the exact make and model of American vehicles. We will always at least try to guide the owner towards what the problem is likely to be in this instance We may struggle with none specific electrical issues related to the a/c without seeing it but it is likely we could narrow the problem down

Experience

Director www.chillywillys.org specialising predominantly in UK vehicles, fleet, rare and collectables. Although all a/c works on the same principal US vehicles have different controls and electrics. 12 years experience automotive and aircraft air conditioning. This is our sole source of revenue, we see lots of a/c issues that we are able to diagnose accurately mainly down to experience. UK have garages caught on to a potential revenue stream within the last few years but sometimes struggle with the problems as they don't see the issues that often........to be fair they could get their own back and ask me to change a timing belt ! Certain vehicles have known issues, we can help with that and also anything that is obvious to us but not necessarily to the bamboozled owner....... a/c is relatively new here and owners are catching on to maintenance but are sometimes still misguided by inexperienced individuals a bit timid to say' I don't really know
