i have a 04 MDX and does anybody have an idea what can be the problem with the A/C it starts cold and then it will start blowing warm air then later on the cold starts again

thanks

 

i was doing some research and found some info. if i have it right about the compressor coil stator could be bad any knowledge of this

thanks

 

Check the simple things first. Have the freon charge checked. Could be a slow leak from a tube fitting / compressor seals.

 

had it check fully charged a/c is cold then gets warm after about 10-15 minutes then cold again

 

Can you confirm wether or not the A/C compressor clutch disengages or not?

Also, do the fans in the engine compartment stay on regardless if its blowing cool air or not?

Two most common things I see here around the shop that affects these MDXs:
1. Evaporator temperature sensor (located behind the glove compartment)
2. A/C pressure switch (located right between the engine comaprtment fuseblock and power steering return line into pump)

Lastly, look around online for the self-test you can do right on the HVAC control panel itself. Its pretty lengthy or else I would post it but a quick Google search should show you what/how to do it.

 

i will definitely do the search but if you can post it i would appreciate

thanks

 

is there any special way to confirm if the compressor clutch is disengaging

 

went to the dealer to check my A/C on my 04 MDX because it would blow hot air after 10 -15 minutes i was told i need to change the clutch and coil and relay and the dealer wanted 1198$ parts and labor are they sold as one or separate items i try to find the parts but came up with just clutch coil part # 38924-RCA-A01 or a/c compressor coil /stator set thanks

Now that you know the problem have a independent mechanic quote you. It might not be cheap but I'm sure it will be less then the dealer.
