96+ A/C Swap

[bajajunkie]

So I have been reading up on the A/C differences between the R134 and R12 systems and there is a crap load of opinions and depending on what you ask about you will get 20 million different responses.

 

With that note ive decided since i can peice together an A/C system from a 96+ cherokee for a little over $60 bucks at the JY I'm gonna try this out. Here is my parts list:

 

Compressor (mine has a bad bearing) $25

hoses $10

expansion valve

evaporator $15

Condensor $15

 

The thing I'm interested in is the elec. fan switch issue. it never seems to be mentioned during these discussions. I know that it is controlled diffrently from the renix era to the the hi output era. If i put this newer a/c system will i need to adress this issue and possibly other electronic components that may not be compatable with the newer ac system?

 

If i forgot any parts above feel free to tell me i fudged up haha

You can just wire up the fan to run whenever the compressor is running. So as the compressor cycles on and off so does the cooling fan.

 

And you want 96- R134a stuff, 97+ will not work for you.

 

I'd also get a new drier and expansion valve while you have the system apart. Not nessesary, but cheap insurance.
