Ok, I was driving the car and I noticed that it was getting hot inside the car, so I turned down the thermostate a few degrees. It didnt help, so I turned to all the way down to 60*, and it is still blowing HOT air through the vents.

Is there a diverter valve that may be opened and not closing?

Also, I did notice that the AC needs to be recharged, I know that it will not get cold without freon, but it is honestly as if the heat was all the way up. The outside temperature was 45*, shouldnt the air at least get cool?

Thanks for the help
 
No, it's not the thermostat.

If he'd come here a little more often and not only when he wanted free help, he'd have known why his LS is blowing hot air.

Hell, even I know and I don't own one... but I do read the Gallant... errr. LS forums.

Maybe if he learned how to search...?
 
I did do a search and didnt find anything regarding what I was looking for.

You must be very gifted, I just wish that I had the talent that you have.
Thanks for the help

Running the compressor on a low charge can destroy it. You Have Been Warned.

As for the heat, search for DCCV. IIRC, the valves are open by default and the computer commands them closed via their solenoids. So when the solenoids die - or valves get gunked up - they don't close. And you get lots of heat.
Simple attempt is just using a coolant system cleaner to see if that can un-stick the valves. Obviously won't help if the problem is the solenoids.
 
possible DCCV

could be gummed up DCCV, we see this every winter as people change over from cool to warm temps, just like clockwork.....the DCCV gets gummed up over the summer months from lack of use.

This may be true, but the DCCV is operated during the summer. If you leave the climate control on auto, when you cool down to the desired temperature, it starts adding heat in to maintain the correct temperature. Even if you set it on 65 and leave it there, the valve cycles to open every time you turn the key off.
 
This is happening to me too, I tried to replace my DCCV and wasn't successful, I didn't have the right tools. I'll have to try again.

With mine the AC Compressor fuse blows every time I turn the system on Auto.

Mine went out in mid September, when it was still in the 80's..
 
i vote for starting at looking at the DCCV as it is one of the parts that always seem to fail.

i would check the temp of the three coolant hoses at the DCCV with the temp all the way down, you should have one hot hose and two much cooler hoses, if you have three hot as hell hoses then either you DCCV is stuck open or the DATC that controls it is sending out the wrong signal.

Damn, we cant escape the jokes about our cars even on our own side of the forum :rolleyes:




also this is definitely something that should be found in a search as it is the most common issue asked about right after coils/engine missing, and "what wheels will fit my car?"
 
lmao....i just looked to see if mitsubishi still makes the galant and yes they do.

and it looks cheap....ugh.
 
Sounds like this thread was getting to be too much titfortat, so skipped most replies.

Hopefully some one told you that 90% it is the Dual Climate Control Valve, aka DCCV. This is that funny looking valve with about 4 heater hoses going into it on the passenger side of the engine near the right of the radiator.


BTW, there is a diagnostic you can do using the push buttons on the climate control panel. Maybe a search will do, or maybe joegr will step in, he knows the sequence and codes.

This is maybe a 15 minute job for a typical home mechanic. The part costs anywhere from I think $100 to $180 depending on where you get it.

Be sure to bleed the air out of the system afterwards, and also check the fuse in the fuse box under the hood. Often it blows when the DCCV dies.

BTW, the fuse controls the AC compressor clutch so the AC won't run.

An easy fix if you know which end of the wrench is pointy. A lot of threads on this, look up DCCV.

Thank you sir. That makes alot of sence. I did not know what the dccv was nor where it was. This is exactly what I was looking for! I will give it a try this coming weekend
Thanks again.

hey at least he's comparing your car to a slightly cheaper version of the same platform, comparing ours to a cheap @ss piece of jap junk, is just a punch way below the belt.

why dont all of us Lincoln guys just team up and make fun of the Cadillac guys together :rolleyes:

See you next time you have a common problem with your LS.

Ill be sure to pm you first buddy. Maybe by that time, you can perhaps buy a LS and have a real reason to be here. Gives you more of a reason to bother people I guess. See you around:)

Check this post I made a few months back. I tell you what tools, and ho many screws are there. Plus I mention how to unplug the wire harness, there is a slide lock you need to move or it ain't going to move.

BTW you don't need to take the DCCV apart, I did that just cause I am cheap and hoped to fix it. Just remove and replace the old one and check the fuse under the hood.


Good Luck,

Jim Hnederson

No need to PM me next time. I'll make fun of you all the same. Might as well let everyone enjoy it.

And no, we're not buddies. We don't drink together, we don't hunt together, and I sure as hell am not interested in knowing your lazy incompetent ass on a more personal level than our current acquaintance status.

Maybe by that time, you can perhaps buy a LS and have a real reason to be here.

I'd love to buy an LS, but they're still a little out of my price range. Maybe next year...

No, it gives me more of a reason to tell people such as yourself to pull your head out of your ass and to stop expecting the answers to your LS problems to be handed to you on a silver platter.
