HELP HELP HELP!!
I had another thread and got a response but things seem to be working VERY different so I am starting over...
2001 PT Cruiser
History- About a month ago fan motor not running. Ac blowing warm. Code said short circuit relay slow speed fan. Bypassed and checked motor, low speed not working. Replaced fan motor and relay worked for almost a month fine.
This week- Suddenly overheating warm ac. No codes. Bypassed relays and checked new fan motor, works on both speeds. Yay. Replaced relay, this time purchased relay at dealer. Plugged in relay, everything works great for about 5 minutes! Fan comes on, ac blows cold. After 5 minutes warm ac, no fan. WTF. The new low speed radiator fan relay fixed it ALL for 5 minutes!
Why does it all work suddenly with a new low speed relay then stops????? If I put in another new low speed relay the same thing would happen.
Update: I took out the new low speed relay, low speed fuse (#5), ac relay (switched with horn). Checked them and put them back in. Everything worked again! Fan came on, cold ac. 2 minutes later it all stopped........ AGAIN! Why does is all work (fan, ac) for a few minutes when I first put everything in then stop??? I'm going CRAZY! HELP!!!
