Question about 1998 Isuzu Amigo
Good day,if my air conditioner is running for more than twenty minutes the blower unit freezes up and air temp gets warm. when the unit is operated for short runs it blows very cold air no problem. where should I focus my attenion. thank you
Check for a plugged drain tube outside on the firewall or in that area opposite your heater & AC. Clear it out with piece of wire or similar to remove any debris. Be careful not to poke too hard or deep & puncture heater core or damage any other part. You can usually see liquid on the ground when sitting with AC on, my guess is yours is very limited now, or none at all.

You need to replace the expansion block which is connected to the evap , it regulates the freon going into the evap . And it tries keep the evap at 32 to 40 degrees. They get stuck open and closed and then need to be replaced they can't be repaired. The freon turns from a liquid to a gas in the evap at low press a TXV or Expansion block stuck open will allow to much freon in and the evap will freeze up. When you remove the old one look at it real good when you unrap the thick rubbery black coating , this is important you put it back over the new unit just like it was on the old one. and the tube coming off the exspansion block is the Capillary tube and buld which needs to go back just as it came off and rerap it the same way. If the rap wont let you take it off easy you can buy some new at the part store. just make sure you rerap the same way. also when you have it off you can flush the evap using denatured alcohol or a/c flush but a air compressor and flush can is need unless you have a way to send air in it. If you dont have a diagram Google the location diagram on line of the expansion and evap . And remember the system needs to be empty before you change the expansion block. and before you charge it back up if you can vaccuum system for no less then 30 minutes this is the only way to remove moister and such from the system and give you cold a/c
