How do you tell if your compressor is shot or if you just have a leak? I know, put dye in the lines and so forth, but no leaks are found when this is done. I'm thinking if I pull the dash out and look in the box with the coil, that will be where the leak is, if there is one. I hope that makes...

Does anyone have any pics or advice for a newbie doing his first heater core flush? Thanks in advance,

My situation is that my 99 XJ was overheating and had the radiator flushed and had multiple issues after doing so. I I was still overheating, blew a lower hose and had no heat. I know, I could have done it myself, but I didn't and I am paying for it. I left it with someone who checked out...

After a lot of hit or miss stuff trying to figure out overheating issues. It turned out that my radiator was clogged/shot after a flush. I won't go into that. the guy that did it put in a 180 tstat instead of the 195. I keep reading arguments for using and not using a 180. What is the...

I had my shop flush the radiator, and put on a new cap and T-Stat, and had a new top hose put on. After I got it back, I started having problems. The next morning I didn't have any heat and after driving it a while, I shot anti-freeze all over and it cut off and steam rolled out from under the...

Ok, my A/C works great when it isn't blazing hot outside. When the outside temp gets over 85 degrees, my A/C will "freeze up" when driving around town. Usually, I have to turn it off for a few minutes, and all will be fine for a little while, then do it again. I've replaced the low pressure...

I've posted something similar before, but....On my 99 I only have trouble when it's hot and humid outside. I work perfectly when the humidity isn't high or it isn't your Summertime VA/NC temperature. Without fail, I'll have warm air and the distinct smell of a frozen A/C system. If I cut it...

In my 99, the A/C works like a charm until I come to a long stop, where the air significantly gets warmer, like it is freezing up. I have to cut it off for about 5 minutes, then I get cold air again. Several years ago I had a part(on top of the condenser, I think) replaced via a TSB, the...

I bought a fuel pump from ebay in early Feb. After it was installed I had the heat soak symptoms of funny starting. I just found out that my pressure is 70+ lbs from the pump. Would it be better for me to give the dealer an arm and a leg for one, or try my luck on ebay again. I matached up...

Like the title says. Can heat soak cause intermittent injector problems with starting? I have a problem with starting only when it's hot outside and the engine is warm. It takes a little more cranking than usuall to turn over. I did have the "vapor lock" problem, but now it's turned into this.

I used to have the vapor lock symptoms, but they have mysteriously disappeared. Now after the JEEP has sat for a while after driving, it will crank and crank and crank, until it starts. Might be the starter, but it seems to only do this after the engine has gotten hot. I want to check the...

Anyone know the proper length spark plug wires should be? I'm trying to track a problem and am trying to boil some things down. When I changed them out, 1 or 2 were a little different. They were close. Would it even matter?

I'm having a starting problem that is REALLY seeming like vapor lock on my 99 Sport. Throttle body, TPS, intake sensors are all new. Fuel pump is new, etc. CPS isn't though. I've narrowed it down to an under-hood problem. It happens when the outside temp is HOT. If I crack the hood, it will...

I'm narrowing down a starting issue that I'm having. When the engine is hot, it will turn over, start, then struggle BAD to stay going for about 15 seconds. It will then rev up to normal and run like a top. I do notice that if I pop the hood, it will start great 9.5 out of 10 times. Plugs...

The 99 Jeep is having a very hard time trying to stay cranked when I start it. I will turn the key, crank it, it will go for 2 seconds then rpms drop to the point that it is STRUGGLING to stay cranked. I usually turn it off and restart to success. Sometimes it takes a couple of times to get...

My Jeep has started struggling to stay cranked unless I have my foot on the gas when I turn the key. It started "surging" while I had a steady pressure on the pedal. To "fix" it, I would let off the pedal and it would clear up for a while. I changed out plugs, wires, cap, and rotor and tps...

So now, most of the time when I start the engine, it kind of sputters like it is going to cut off, then idles up to normal after a few seconds. I've been chasing a surging type gremlin for weeks and I'm wondering if the 2 are related. I've thought: dirty filter and intake, cleaned, bad tps...

I'm getting a surging sometimes when keeping constant pressure on the gas pedal. Plugs, wires, rotot, cap, and TPS are about a year old. I just replaced the coil to try to help, it didn't. Throttle body was nasty and has been cleaned.

I'm getting a surging sometimes when I am keeping even pressure on the gas. I've changed out the coil, and the plugs, wires, cap, and rotor have 20-25k on them. TPS is about that old. I've been wondering about the CPS. Is it one of those things that either work or don't? Thanks in advance

Anyone know where I can get the details on TSBs? I've got the list from Alldata and I would like to know what to expect for a repair. Thanks in advance.
