I have checked numerous sites about heater core replacement in a 98' Durango and all but your site say dash must be removed to get to it. Is this true? This is in my daughters car and was thinking I would have to take to a shop and pay around $1000 to have done. The other sites also say you need to evacuate air conditioner and disconnect airbag. Please provide more information.

Thanks

All of the above is true! Instrument panel, A/C discharge, and even steering column is advised, but not mentioned..Air bag disable too!

Location will be on passengers side near firewall, behind dash. REMOVAL INSTRUCTIONS: Disconnect the battery negative cable. Remove the instrument panel from the vehicle. If equipped with air conditioning, recover the refrigerant. Disconnect the liquid line refrigerant line fitting from the evaporator inlet tube. Disconnect the accumulator inlet tube. Drain the cooling system. Disconnect the heater hoses from the heater core tubes. Remove the four nuts from the heater-A/C mounting studs on the engine compartment side of the dash panel. Remove the nut(s) that secure(s) the heater-A/C housing mounting brace to the stud(s) on the passenger compartment side of the dash board.

Power door locks, windows, blower motor, and interior lights don't work. Radio turns on when door is open along with climate control back light. Replaced heater core and not sure all grounds were connected to appropriate place. Fuse box has power to it. Components started failing 2 weeks after heater core replacement (blower, then interior lights, then door locks, and finally windows). Please help. I have reached my limit of knowledge and have no one else's brain to pick. Thank you.

You need to check the ground connection at the right kick panel. There is a nut with two big ground wires. Make sure it is tight and clean.

If the grounds are OK, check the Central Timer Unit (CMT).
To get to the CTM in the 1999 and 1998 Dodge Durango take out the globe box and there will be a panel to the right. The are four screws that hold it in, take them out then the panel and the CTM will come out. The CTM will have a white and green connector connected to it.

there are thre grounds for locks windows an dinterior lights at lh rear of body see if that has broken or dirty. also on lh side of dash for interio lights.
