I have replaced the vacuum module and the solenoid on the firewall, on occasion if engine is cold and u turn on defrost it will kick into 4 wh low.Also heat it sketchy at best. Will warm up and have heat for awhile and then gets cold. Replaced t stat and now suspect water pump has internal problem. Any ideas

I have replaced to vacuum solenoid and booster or whatever its called on the front diff.I heard somewhere that if you put the heat on defrost and then engage the 4 wh that a specific vacuum line is bad . I tried the defrost thing and 4 wh will kick on low only. I cannot find a bad vacuum anywhere. Please help
