Re: Blend Door (with pictures and the common problem)
ok so i seem to be having the same problem kinda. my system was low on 134a so i topped it off. not the compressor stays on like it should. it will blow cold air for about 3 seconds then switch to head for 4 or 5 sec. it repeats no mater what setting i have it on. i have a 99 envoy. i don't know history of this vehicle as i just bought it this way. any thoughts? blend door swiging? no noises or anything. im lost!
99 envoy
has auto climate!
clutch not slipping.
compressor is working!
right pressures on system!
i realize this is old but i only have seen this thread as being what i am going through and need a bit more help!
