Re: 1993 Jeep Cherokee A/C Performance Issues

The original condenser was a Serpentine design that worked well. If it was replaced with an aftermarket part of a different type, it is hard to say if the condenser is up to the job. Jeep went several years where they could not make up their mind on fans. I believe your 1993 should have an engine d...

Re: 1993 Jeep Cherokee A/C Performance Issues

Thanks for all the responses guys. To follow up on some questions. When I sprayed down the condenser the low side dropped to 40 psi and high side was around 225-250 psi. I didn’t take a reading at the vent to see what it dropped down to. I would take a guess that it dropped about 10 degrees from 70 ...

1993 Jeep Cherokee A/C Performance Issues

I’m having A/C issues on a 1993 Jeep Cherokee with a 4.0L engine. The background on this Jeep is that it had an original R-12 system that worked well up until it was wrecked two years ago. The wreck damaged the condenser and I believe this ultimately led to it leaking out all of the refrigerant. Bel...

Re: No A/C after cooling fan melt down

I am by no means an expert here, but having some familiarity with this A/C system (have an ’07 TL Type S with the same J35A8 engine, and is probably very similar A/C system to that) I thought I would chime in. I had an A/C related issue on that car in which the A/C clutch relay failed in the closed ...
