hey guys, so i recently ripped apart my vaccums lines because i got tired of it not engaging even thogh it sucked i found that alot of the lines had cracked so i cut them where they were and put rubber house 3/8ths over it, anyway the constent sucking was always there ( keep in mine i have a 99 tj 4.0 HL engine in my jeep but all the rest is 89 yj) when i engage the trasnfer case it immediatly kicks in and the same when i turn it into 2H. anyway i noticed it knocked really bad sometimes and took miles to kick in so i permanently locked the front axel with washers and it kicks on and off but the issue i have now is the 4x4 indicator light when i bought it the guy had it covered with a gay sticker removed it and it does NOT light up at all, the sucking is there i ripped apart everything to replace it with newer lines but still nothing. any ideas ? i can replace the siwtch motor on the TC and keep in mind i dont have the clip near the acuator that locks it its the old style one. any ideas guys anything would be appreciated.
