I have a 2004 Durango (Hemi). The front air blows at 54 F and this
week the rear air started blowing warm. Is there a fuse for the rear
cooler? I don't understand how this system works, so my questions
probabaly don't make sense. But why would the front be cold and the
back blow warm don't they come from the same compressor?
Please help me out.
Suddenly, without warning, dirtclod exclaimed (8/28/2009 9:01 PM):
You're probably out of refrigerant. When this happened with my 2001
Dakota, the evaporator needed to be replaced.
You could try buying a can of refrigerant with a gauge and dye, see if
you can fill it up, then look for leaks with a UV light - but if the
2004s are like the 2001s, you might not find any 'cause the evaporator
is inside the firewall.
The stuff I used is - if I remember right - R134a, but I've no idea if
that's standard; check your truck's manual.
Cost me about $1000, mostly labor to get to the durned thing (and put my
dash back together after), to replace the evaporator.
First off, I thought 54F was about right since I am in Central TEXAS
where it is 105F outside.
Second, the rear air is much warmer than the front. Probably 20
Third, I wasn't asking you to guess.
And lastly, I know it's broken, I was looking for some helpful advice
to understand the system, not a smart-ass reply.
Thank you to the other people that replied. PeterD is obviously over-
compensating for something.
And I disagreed with you? Don't remember doing that.
Bring it over and I'll do proper diagnostics. Online a guess is as
good as it gets.
OK, ignore my smart-ass replies then. I'm sure someone will come up
with a non-smart-ass reply.
Thank you too. Even if you didn't like my advice.
The lack of sense to not reply to your post. Won't happen again, good
luck hope you get it fixed.
Now, re-read my original reply, take it to a qualified A/C shop and
get the charge checked. Or, just piss-off, I don't care.
The ones that don't know the answer but spouts some crap off message. The
old Citizen Band radio had a lot of those people. They don't amount to much
but clutter the newsgroup and back then the airwaves.
You're right George, he had no idea what he was talking about. It had
nothing to do with the refrigerant charge. The blend door was broken
and burned up the motor. It's fixed now. No thanks to the lame
advice from PeterD. If you don't know what your talking about, keep
your mouth shut and you might learn something. That is why you have
two ears and only one mouth.
Did you take it to a qualified tech? If you did, then you followed
PeterD's advice, which wasn't bad by the way. As a matter of fact he was
the only one who told you to take it to a qualified tech.
How come people have to ask a question and then start a pissing match
with someone who gives a GOOD answer?
