I have a 2004 HiLo trailer and my heater is not working, blows air but no heat, worked good last year but not now. what I am looking for is PICTURES of where to look for the sailswitch. I have tried YouTube and they tell how to fix it but not where its as to even see it. If I can see where it is I can decide to either do myself or get a pro. I believe its a suburban and its a small trailer only 22 ft s the heater is not large. I hope someone can help me with PICTURES. Thank you, this webpage has always been helpful in the past I hope you guys can come through again for me. Scott
