Re: ac problems

Ok, the fan clutch is shot. With a 79f ambient you need the fan. Replace it. The third reason for short cycling would be cycling on the HPCO - because of high pressures caused by poor condenser performance. Try spraying some water on the condenser while the system is running, and see if the cycling ...

Re: ac problems

It sounds lie your compressor clutch is short cycling. There are a couple of reasons for that to happen, either low ambient temperature or low charge level. Some more information would help. What sort of temperatures are you seeing where you are located? What model year is the vehicle? You say the c...

Re: Toyota Sienna rear air weak

The good news is the rear evaporator assembly is not too had to get at... They hold a lot of water when the drain plugs up. Check out how much water this guy drains out of one: https://www.youtube.com/watch?time_continue=174&v=eOm4svPZKgM Now try to imagine what that water will do to actuators, ...

Re: Thanks for the add and RV2 questions

Clutch should draw 6 to 7 amps. A relay could be used, most new cars have clutch relays because the computer is involved in the operation. The headlight relay mod on early Mopars is a big help. Really any relay that sheds load from that 50 year old harness helps. I did headlamp relays along with a c...

Re: cold weather, low pressure, cut-off point?

Knowing that a system is low on refrigerant months ago? STOP running it. With no refrigerant to return the oil, the compressor runs dry. A jumper wire can cost you a compressor. You can charge the system when it is 20f out - if you have the equipment. The system needs to be recovered & evacuated...

Re: Thanks for the add and RV2 questions

I just added an external shunt for the ammeter.

I did finish the rest of the electrical, that thread is a few years old. Car still needs paint... Old Mopars are never done.

Re: Thanks for the add and RV2 questions

Yep, there should be a temp control switch with a bulb stuffed in the evaporator. I am guessing this is a B body. The poor fan performance can be several things. Obviously check the ground at the fan motor & the overall health of the motor itself. Power connections from the switch to the motor, ...

Re: What would cause this new compressor failure

Looks like a clutch failure, the compressor may be ok. High head pressures can cause a clutch to fail, but there are usually other factors that contribute. Was this an aftermarket compressor? Clutches perform best when they have been burnished a bit, and are dry & clean. The fact that you had a ...

Re: Two Condensers connected in series

And there it is. 3 to 5 times a year, every year for the 12 years I have been on this board the same series of questions happens. 1)" My A/C sucks at ide / overheating at idle" 2) Questions about engines, parts, etc. - this can go on for pages. 3) "I got rid of the OEM fan(s) for spac...

Re: Two Condensers connected in series

By 1998 those cars already had Parallel Flow condensers. Your OEM unit is 25" x 15" . Just make sure it has enough airflow. Your car was an OEM electric fan vehicle, so make sure all of the seals, dams etc. are still in place for best airflow from the OEM fans. The pusher fans can be good ...
