mine was clogged up last year and was the orig to my truck (amazin!!) so i did like you and searched on the process of how to change it. some said "ya gotta pull the dash down" and others sugguested "at" it but i couldnt get a stright answer on the process so i dove in and step by step broke it down and it is easier to do than my firebirds and doing one on my birds is a 45 min job and thats even pulling and putting up the tools.Yea I have never seen one do like mine did. But I turned it on this moreing and no steam? I dreed the hell outa this. Any tips on goin about this?
