Great switch at a great price arrived on time
Couldn't be more pleased Didn't think I needed the switch so I requested a return, I was emailed informing me they would issue a refund but no need to return the item. Once I began my repair I realized I did need the switch so I emailed asking they refill me for the item in which they did not do. I felt bad over what had happened so I will certainly use 1A AUTO again in the future.

No More Sweating!!
Had the part for awhile because I thought there was a piece that needed to hold the switch housing from slipping back. I had a mechanic put the part in. Said he couldn't find the part but since I did, through 1A Auto my A/C works great!! Thank you A1. I won't be sweating in the California heat this summer!!!

What holds the 1997 Toyota T100 Heater Fan Control Switch HVA01079 in place so that it doesn't slip around? Sonethibg missing?
The tabs on top of the switch slide in to groves in the assembly but they get brittle and break off so I just super glued mine in
