If your 1994 Honda Prelude V-tec is not getting power to the AC fuse under the hood is there another fuse behind your dash somewhere that you need to change so your AC will blow cold?

Answer 1

Preludes have a probelm with the Climate Control (CC) circuit boards; after a while the solder will break loose. To fix: 1. Remove the whole radio assembly. {Console 10 screws; Radio 4 screws} NOTE: It is easiest to remove the 2 connectors on under the CC now while the CC box is still fastened in place. There is a tab on the bottom of each that you have to hold down as you pull. 2. Remove the climate controls and center vents all as one unit (careful of the temp cable - you have to undo the screw in the end of it.) IMPORTANT: Remember how the cable clips back into place so that you can hook it up the right way. {3 screws facing away from you on the bottom front support; 1 screw underneath CC in the middle, 1 screw holding temp select cable} 3. Remove vents from the CC {2 screws in the back} 4. Remove temp select smaller circuit board from CC box {3 small screws} 5. Remove lights on top of CC box. All you see of these are the white plastic bottoms. Turn ~1/4 turn and they should fall out. 6. Unclip and pull off the casing from the front of the CC controls. IMPORTANT: DO NOT REMOVE THE INDIVIDUAL BUTTONS!! YOU WILL BREAK THEM IF YOU TRY! Yes, that's personal experience. {1 or 2 small screws} 7. You should now be looking at a circuit board. Resolder all of the pins the lead to connectors at where they are soldered to the board. If you are not comfortable with soldering, find someone who is...the solder cannot be touching! "Cliffs" on soldering: (A) Using a soldering iron heat the backside of the pin (couple seconds), be careful not to puch the pins through the board. (B) Apply solder to where the tip of the iron meets the pin - the solder should distribute itself pretty evenly around the solder all ready there. (C) Repeat until all pins are done. 8. Steps 6-1 in reverse. 9. Enjoy your a/c that now works and your fan controls that now actually change where you want them too. --This took me about 2.5 hours total, but I didn't have any directions to go from. The biggest problem I had was getting the temp select cable to clip back in place. Make sure you try it out a few times before you put averything back in to make sure it works like it should and doesn't slip out if it's clip. --Also should probably remove the battery cable before you start. I didn't and had to replce the radio fuse so I must of shorted it out somehow.
