Yes, Another a/c question

My a/c was blowing cold when we went on a long drive ( 4 hrs up and then next day 4 hrs back )Then next morning all it did was blow hot air. Clutch is in engaging , check freon thats ok,all the a/c lights on dash comes on and so it hasn't worked in 2 weeks. Could it be the thermo control amp that I keep reading here. Thanks for any help. I know it's winter but I live in Florida.

Hello ??? What else could just go bad to cause ac just to quit blowing cold air ? Just got a 2003 xterra and I know nothing about them..Thanks for any replies

If everything checks out the thermo control amp could be it. I had the same problems and replaced mine. That was the problem.

thanks for the reply, I was just wondering since most threads that i read said the a/c would work sometimes, but mine just quit one day & hasn't work since. I didn't know if something else would just make it stop working overnight.

Where can I get a "thermo control amp " ? and what is the correct name for this part thanks..

Thermal Control Amplifier

please , can someone tell me where I can get a "thermal control amplifier" for my 2003 xterra.Thanks...John

Hmm, that's a tough one. I wonder if a dealer might be able to procure one?

Before I look and drive to a dealer,get surrounded by salesmen, convince them I don't need a new nissan, then try to convince the parts guys that I don't need to bring my xterra in to hook up to computer to find out what is wrong, then pay $120.00 for a $30.00 part. I would like to find a place online to buy. I have tried a search and found a link to one but it was for a 2000-2002 xterra , I have a 2003. Every nissan web site that I have been on doesn't list one or when I try a search on their web site for a "Thermal control amplifier" it comes up empty. So thanks for the last reply. You must work at a dealership

Dunno if this is what you need, so you might want to call them.

Thank you very much, this is what I was looking for...

jeclair, did the TCA fix your a/c problem?

I just got it, plan on putting it in this weekend. I will let you know. I just moved from Ocala about 4 years ago after living there for 15 years, nice place if it's Ocala, Fl.
