My 07 TL has always blow cold air from the A/C and all of a sudden its not getting cold at all. What should i do?

 

Have the A/C system checked.

 

some simple tests for finding the leak that you most likely have

A.

1. Open hood
2. Start car
3. Turn on AC
4. Go to engine and check to see if compessor is working (you will hear it click on and off an the engine change RMP at the same time)

If your compressor is NOT turing on and off do Step B

B. Get some R134a with the flourscent die in it (one of those recharge kits). Any brand will do

1. Open hood
2. Start car
3. Turn on AC
4. Connect hose to can following directions
5. Connect other end to LOW SIDE (the hose only fits the low side)
6. add just enough of the R134a with dyle to get the compressor to kick on
7. Take a LED (not the regular incadescent) flashlight and start looking for leaks while the engine is running. BE CAREFUL as there is a few moving parts that CAN SERIOUSLY MESS YOU UP

My guess is you are going to find a hole in your condensor and see the die coming out. If the condensor checks out fine, shine light at compressor and check the shaft seal. Next follow each line from compressor to fire wall and check. It is unlikely the lines will leak from the aluminum parts but more likely at the ponts where they connect to the rubber flex hose.


Take care to Acura dealer and give them $400 to replace condensor and receiver dryer or slightly less for a leaky line. Make SURE they replace the receiver / dryer unit

 

Many threads, and several possible reasons for your problem. This link contains some ideas, and other links, which may help you. Just because the link is for the RDX, A/C problems occur for all models of Acura/ Hondas, so read the link before deciding it is not applicable for your TL

That happened to me 3 weeks ago. Tried replacing the freon it worked for like 10 minutes. Took it to a shop and the entire compresser was shot ended up costing a small fortune.

 

To the OP:
continuing to run the A/C compresser when it is not cooling, can damage the compresser. If the problem is no or low Freon, since the compresser lubricating oil is suspended in the Freon, then there is no oil, the compresser bearings self-destruct, and spread metallic junk throughout the entire A/C system.

That requires replacing the compresser, lines, condenser, accumulator, and if you are unlucky, the evaporator. That is why it can cost a *fortune* to 'fix' an A/C system. Its the labor that is the major cost, although the parts are not cheap either.

And sometimes its just the compresser clutch that is bad, as indicated by a recent Acura TSB for the RDX, and the extended warranty for the 1st gen RDX.

Replacing the clutch alone is only $150+ for the part, and much cheaper than replacing the compresser, since it is not necessary to disconnect the Freon lines, and replace the Freon. Of course, many shops will just want to replace the compressor (with clutch) because its easier, and much more money to their bottom-line. Use a shop that you trust, and get a second opinion.
