Replaced all four oxygen sensors. Replaced heat sensor, replaced electronic gas pedal and electronic and module .

Every time you start the vehicle

the connection looks fine

the truck has been parked for about a week and today I went to turn it on and it all worked fine but the AC on driver vent did not blow cold only hot, every other vent blew ice cold

I've had this problem about 4 years ago,I turned the vehicle off and started it back up just fine... I've tried it this time & the rpm still won't change

it only does it after it gets drove a little and it loses power and goes all to crap.

I'm having what I think is an electrical problem. All of a sudden all lights are the dash are on, radio won't work, a/c won't work, drivers side window worked for a little, now not at all and no other windows work, interior/exterior lights work, although not automatic, automatic doors do not lock but you can lock manually.

ing. Radio turns off and on. Replace battery, checked ground wires, any idea why this is happening?

in cold weather noise is more noticeable
