No . it will not affect the cooling. If the compressor was replaced because of internal failure it is possible that there is metal stuck in the TX valve orifice preventing full fluid flow to allow the evaporator to work properly. Basically how an ac system works is this . There is gas in the system. A compressor turns this gas to a liquid in the condenser. This is achieved by the TX valve restricting the flow to the evaporator ( bit under the dash). As there is a low pressure in that unit from the compressor trying to suck the gas out then the liquid is converted back to gas ( boiling off quickly from the heat in the car) which cools the air around the evaporator . The process is repeated . IF the tx valve becomes blocked or overloaded by excessive compressor oil then you have problems with cooling.. Have it checked out by an accredited ac specialist shop as the differating pressures between the suction and high pressure sides of the compressor will reveal why it is not cooling.

it is inside the right rear corner of the van with line connections under the van you will need to remove the plastic cover inside the rear corner

You'll have to replace the evaporator if it leaks. The part is kind of expensive but is available aftermarket. Use 134A. I can likely post the removal procedure.

where is the rear evaporator core located on a 2004 chevrolet cavalier

new spark plugs basic tune up this will fix it ,then fine the small vacuum leak fix it this should take care of it.

see if it needs freon first,if not replace the expansion valve it is trying to close up

Plugged drain tube.

Check under the hood, on the firewall, passenger side. Tube comes off the bottom of the evaporator housing (this is the box where the a/c lines enter the firewall). Usually a rubber tube that directs condensation from the evaporator housing to the outside. This tube often plugs with dirt.

I don't know of a step by step sheet for this procedure. This job will require you to pull a vacuum and then do an electronic leak check once it is completed. This is an expensive repair, so you must weigh the possiblities of doing without air , or paying a technician to do it properly for you.
