hvac

Time of the year where I try and fix my heat before a cold winter… again. So I’ve done some more research and poked around trying to find what this issue is with my heat but no luck fixing it. Here’s what I’ve found: Flushed heater core with hose, both radiator hoses are hot to the touch when...

Hoping someone can help me. I just bought a 6 owner 99 Sahara. Surprisingly, it has only been minimally Frankenstein’d. On thing that irks me is, one of the connectors on the hvac pigtail has been cut. It appears one of the previous owners tried to hardline from blower resistor to some wires off...

Any thoughts on this? This morning it was a chilly 31 degrees here in Chandler, AZ. My jeep is not a fan of cold weather and neither am I. Anyway, I started it up and let it warm up to about 150 before backing out of the driveway and heading out to run some errands. As soon as I turned on the...

2006 LJR has good pressure, aluminum lines are getting cold, there's air (room temp) blowing from all locations when they're selected. In my experience, these symptoms usually indicate a bad/clogged cabin air filter, but since the Jeep doesn't have one, I'm not sure where to begin. Has...

I have referred to the forums over the last 2 years regarding intermittent blower motor issues. It started when it was not functional at all. I initially replaced the resistor and the blower motor and it worked for a period of time before failing again. I then replaced the switch panel and even...

My HVAC controls only blow on the lowest level. I replaced my blower motor resistor and it didn't fix the problem. At two random moments during driving, my hvac controls randomly started blowing on the highest level but this was out of my control and I didn't do anything for that to happen. I...

Hello, I saw the post about the 4mm leds for the HVAC bulb replacement from superbrightleds.com but since I'm purchasing from Mexico I was wondering if you guys know if this leds from Amazon would do the trick for the replacement, thanks! https://www.amazon.com/dp/B013HJGOAA/?tag=wranglerorg-20

My heat and air conditioning work on my 2001 4.0L TJ. Only the first level seems to be the one blowing no matter what level I turn it to. I can turn it to the fourth level and it will still blow at the same rate. Is this more likely to be a blow motor problem or a control panel problem?

Up for grabs is my 2005-2006 Jeep TJ/LJ HVAC (Heater Panel) for Jeeps with AC. This also has real machines aluminum knobs, black anodized with machined accents … very cool. The units works perfectly, no evidence is ANY head damage, not even a hint of discoloration. And being AZ (and garaged)...

Hi all, first post after returning to the TJ club after a 15 year hiatus - picked up a 2005 TJ SE (with the 4L) and will have a list of to-do's for it. Right now as winter settles in, what is getting me most is diagnosing the HVAC issue that seems to hit plenty others where I am only getting...

I know this has been covered before but I need advice. All 4 fan speeds went out earlier this year , This has happened multiple times over the years. I have a 2001 & I've had issues all kinds of issues with over the years but the HVAC issues @ 2004. I replaced the Blower Motor last year for...

Had the ac evaporator replaced. It wasn’t done right. There has to be a wiring issue. The fan only works on 1 speed. As soon as the heavy system is turned on it surges the RPMs. I’ve replaced the fan switch a little while back and the fan switch has been spliced in as it had previously melted...

Got in the Jeep this morning (97 TJ 4.0 5sp) and the A/C would blow in all settings but high. Saw threads about the opposite (high only working) but not all but high. Any obvious paths I should check?

Hola. I dont know much about the heating and cooling system. I just know I had AC in the summer and in the winter I have heating. I am in NJ where temps have fluctuated anywhere from 25F to 48F. Images attached. I noticed when I turn my car on that the lines are completely white and frosted. Is...

My 2001 wrangler blower will not turn on unless it is switched to defrost or defrost/feet vent. The actuator is working and the blend doors are functioning. I replaced the resistor. I have searched for vacuum leaks without finding one. I am a complete newbie to HVAC, and everything I know is...

Fixing some old wiring. Can someone tell me the order of the wires at the back of the selector switch? And at the blower motor, does the black wire go to the battery or back into the harness? Chasing down some very old problems that the PO seemed to have figured out but isn't around anymore...

No matter which setting I put my HVAC control to a decent amount of air still comes out on the floor. What and where to I look for and how do I fix it?

Hi, all. After having finally had a local shop replace the heater core on my 2004 TJ Sport (4.0L / 5speed / AC), I've got great heat, and great airflow (all fan settings), but a not-so-faint smell of antifreeze in the cabin. Not losing a drop of coolant, and never seeing anything past normal...
