'07 Dodge 6.7 CTD intermittent air conditioning

[LwnmwnMan2]

Just had the compressor replaced at 49k miles , along with other associated work.

Now air doesn't work when setting still, although for a couple of days it worked and was ice cold.

Didn't work setting still from the shop, then worked for a couple of.days, now just quit working again.

Dealer said clutch fan was out, that's why it works going down the road.

This will be the third.clutch fan this truck will have if that's the case.

Make sense?

Try to see if it has too MUCH pressure in the system.

Different vehicle, 2002 Kenworth, replaced AC compressor, worked for 2 days then that's it. I figured it lost freon, got a new can, attached to gauges and it was all on red zone. I tried to see if really had that much pressure by pressing the valve with a plier. It shot it up to the ceiling.

I evacuated quite a bit of it and now works like a champ, I enjoy every day in the truck.

Try to see if you have too much pressure, there's a high pressure sensor that will disconnect the clutch when too much is detected

I'm in the truck, trying to cool down between lawns and the compressor keeps cutting in and out. It will run for 2-3 seconds, then kick off for 4-5 seconds. Keeps doing that cycle.

the only way to know what it is doing is with a set of gauges. To me its sounds like it is low on charge.

Too much charge.....

Earlier I had it idle for about 5 minutes, then when I got in the truck it was ice cold.

Now I just hopped in it and sitting here typing this on the Droid, the air has been running on recycle and it's getting quite cold just sitting here again.

What did they charge you to replace the compressor?

My truck has had no AC since the warranty ran out, 3 years ago. This year i bought the can and valve set up and charged it and it worked for a day. Now the AC light on the dash doesn't even light up when the button is pushed. (I have an 05 Ram Cummins)

Just curious what damage i'm in for.

A good majority of a/c repairs fall into t he 500 to 1000 dollar range. I've had a couple over $1400 dollars and I had one the other day that was under a $150. be prepared to spend a grand and hope it's a hundred and fifty bucks!

[LwnmwnMan2]

Mine was just under $1,000, by about $80-90.

It was the compressor, recharge, o-rings, labor and some other things I can't remember at the local Dodge dealer.

It worked earlier again, but then on the way home I could tell when the compressor was running and then stopped. It was instant cool, humid, cool, humid.

I'm going to bet you are going to pay t least that again to replace your leaking EVAP core!

[PurpleFloyd]

I hope mine doesn't have any issues with this weather we are having.

I'm going to bet you are going to pay t least that again to replace your leaking EVAP core!

Then the dealer better come up with another $1,000 worth of landscape work again.

Now the truck idles fast, sometimes. As soon as you put it in park, it idles at 1000 rpm. Typical is about 800+/-.

Temp gauge rises as well, then when you take off, auxiliary fan kicks in.
