PEAK PUTTERS

Anyone have a shop they would recommend, reasonable rates and fair parts prices?

Stay away from TC Battery like your life depends on it.

Or

Have Lurch do it.

What's wrong with the AC? I've done them enough times to be dangerous. . .

I'm booked up till mid April. What's wrong with it?

I agree with OG on this one.

maybe I can help working on a motorhome this week but depending on what you want done

initially when i bought the jeep in 2010 a fuse was blown under the hood. no need for it in alaska so i never worried about it.

after a while is seemed to be getting noisy even though the fuse was blown and the clutch was not engaging. i removed the A/C serpentine belt and put a non-A/C belt on and it quieted down because the pulley on the A/C clutch on the compressor was not moving.

so fast foward to present day in a location where A/C may be needed and I started troubleshoting the system. tested the resistance on the clutch and it was good so I replaced the fuse. turned the A/C on and the clutch did not engage. Checked the low pressure switch and it is closed as is the high pressure switch. so it's probably not one of those. did the old relay swap under the hood with another relay and both relays are operational. what i did find is that the relay under the hood is not getting it's ground from the ECU? which i assume is related to the inputs from the dash mounted HVAC controls (cold/hot position) and fan speed. i can manually engage the clutch by applying 12 volts. i can get the clutch to engage by adding a ground to the relay under the hood as well. i even put jumpers in the connectors for the hi and low pressure switches with no success.

so does all that make sense?

need help on the motorhme?

Should be fine on mh just doing brakes. If you are not in a hurry I can help you out with it as soon as it leaves I have access to recover and charge what year is your jeep I assume 4.0. Ill pull up schematics tomorrow

Check the inside fuse box. The power for the switched side goes through the inside. I don't believe that you will get power or ground to the clutch if that fuse is out. I think it is #11 behind the dash.

Test the dash switch next.

Then. . .

Unplug the computer and test continuity between the two ends of the wire that goes to the relay. It goes, in series, through both switches. Since it is a ground switch, you can also use a piercing test light to see if it grounds out just outside the connector when you turn the switch on.

OG--Had already checked the inside fuse and it is good.

i have to first get a wiring diagram.

I have diagrams printed off for you

when you want to lok at it, weekend or weekday?
