I will start my checks tomorrow. I think what is happening is the system is freezing. The lines into the black box are cold so I bet it is the evap, drier or condensor

Follow-up Post:

Where can I buy the drier, condessor, etc?

maybe the wrong thread to post in but I'm looking for a way to minimize all of the heat that comes into the cab. The A/C works great but the heat that comes in under the seat and the footwell and dash is terrible. Anyone tackle this and have pics?

Do I need coolant or do I have a nice bigger issue that I don't want to deal with? I don't think the AC has ever been recharged.

Can I get one of those kits at pep boys to do it?

I second the dynamat stuff. Its great but expensive. I used some similar stuff I bought at Pep Boys and it worked just as well and alot cheaper.

Barry - I got my D110 Drier from Mike at Westchester PA LR Dealership I think. He posts here. Dealer number is 610-436-0600. Not sure if they can get a condensor or not or who else may have those. I'd say its doubtful your condensor is bad since its just a radiator so unless its leaking it should be OK - though may be clogged with crap but that can be fixed with an AC flush. Or the fins are plugged with mud and dust and you can hose that out to clean as well. Your condensor fan is what I would check.

If you are freezing up, you would likely see your AC compressor shut off. On the front side of that black box, you will see a square silver box with two wire connectors and a temp probe coming out of it. The temp probe goes into the black box on top and rests in between the fins on the Evaporator inside that black box. If that freezes up, it sends a signal to shut down the compressor. The leads from that square silver box are in series with the pressure switch on the drier - so either one can shut the compressor off.

So make sure you find out if the compressor is running or not when its blowing warmer air (and the condensor fan also).

thanks. I will let everyone know what I find. From memory I feel like the compressor shuts off. If the fans work but the compressor shuts off can I assume it is the drier or temp probe? Can I replace either by myself? I don't see a place online to order the dryer

So I did as everyone said and guess what, one fan is seized, and one barely moved. I checked the fuses and it was blown. I put a new one in and it blew. I cant even turn the seized one. This has to be it right? Would explain why after the car gets hot it wont blow cold. So where do I get fans?

I pulled a Ron and installed the fans last night at 10pm. They are working great. I still think the AC could be cooler and am convinced when moving it is colder. If I do the dryer can I do this myself?

Are those the Perma-Cool ones?
Do the fans blow towards the engine bay?

Yes on permacool
Yes on blowing toward engine
As for wiring it was a no brainer. Red to red and lack to black. The fans spin clockwise

Jon,
I have a couple of these arriving this week if you want to take a look in person. Although it may be the weekend before I get them installed.

I thought you just replaced yours?

If anyone has any questions, it was straight forward to do. I bought the fans from Summit Racing.

Jon,

I will refund your money, err rather I will not cash the check (it is still sitting on the counter) if you can't get them working (I am good like that: full satisfaction or I make it right). Both spun when I hooked up power to them before i shipped them out so maybe check the wiring. PM me with the results.

Ron

PS it is possible you mounted them backwards and that is why you had to reverse the wires?

Wow Ron thanks!!!
The reason why I did not bring this up was because I thought they were both running when I first installed them. Then the next day I double checked everything and one was not spinning. I plugged the non-working one into the power cord of the working one, and it still did not work. So long story, I was not sure what happened.
I first had them spinning so the air goes away from the engine, and drove it around the block that way. Latter that day I got to thinking that they should blow towards the engine. So, I am not sure if I killed the one by driving as it would be working against the air flow when moving.
(reversing the wires will change the direction of the fan)
Do you want me to send the bad one back with a $50 check and you can tear up my first check?
Please advise...
Again, thanks...

I will tear up the $100 check. $50 for the good one would be appreciated, but not required as you were so troubled by them. No need to return the bad one. As far as reversing the wires, I think you can actually flip the fan and there is one way they should be mounted so make sure you got that part right.

Ron

OK back on topic. Where can you get the dryer and do I reallyhave to drain the system yet again to replace it?

Just scanned this thread. I've had the valve the regulates heater core water flow go bad on my twice. So you get hot water running through the HVac box while the AC is running. Also have had issues with the cable that opens/closes this valve. One sure check is to put a hose pinch on one of the heater core hoses to close off the flow 100%, and see if that makes a difference. Zero hot water = colder AC. Duh....
